Therefore, the area of the shaded region is 45 cm 2. Let’s see a few examples below to understand how to find the area of a shaded region in a triangle.Ĭalculate the area of the shaded region in the right triangle below.Īrea of outer shape = (½ x 15 x 10) cm 2.Īrea of unshaded inner shape = (½ x 12 x 5) cm 2. Let us understand this through examples: How to find the area of a shaded region in a triangle? How to Find the Area of the Shaded Region?Īs stated before, the area of the shaded region is calculated by taking the difference between the area of an entire polygon and the area of the unshaded region.Īrea of shaded region = area of outer shape – area of the unshaded inner shape The shaded region can be located at the center of a polygon or the sides of the polygon. The area of the shaded part can occur in two ways in polygons. The area of the shaded region is the difference between the area of the entire polygon and the area of the unshaded part inside the polygon. How to find the area of a shaded region involving polygons.This depends upon the type of figure given. Or we can say that, to find the area of the shaded region, you have to subtract the area of the unshaded region from the total area of the entire polygon. Such questions always have a minimum of two shapes, for which you need to find the area and find the shaded region by subtracting the smaller area from the bigger area. The area of the shaded region is most often seen in typical geometry questions.

Perimeter of the rectangular field = 2 x ( Length of the field + Breadth of the field)įence to be erected on 240 m at a rate of 200 per meter.Ĭost of fencing = 240 m x Rs. Find the cost of fencing a rectangular field of 70 m length and 50m width at the rate of Rs. So, the length of the third side is 65 m.Įxample 7. Perimeter of a triangle = Total length of all the three sides Perimeter of a triangular field is 145 m. So, length of each side of the square is 139 cm.Įxample 6. Perimeter of a square = 4 x A (A = Length of each side) So, the length of the rectangle is 176 cm and breadth is 88 cm.Įxample 5. Length of the rectangle is double the length of breadth. Perimeter of rectangle = 2 x ( Length + Breadth ) Length = A & Breadth = B If length of the field is double the length of it’s breadth then find out the length and breadth of the filed. Perimeter of a rectangular field is 528 m. Perimeter of the above figure = AB + BC + CD + DE + EF + AF Find the perimeter of the below given figure. So, the perimeter of the polygon is 68 cm.Įxample 3. Perimeter of the polygon = AB + BC + CD + DE + EA Find the perimeter of below given figure. So, the perimeter of the quadrilateral ABCD is equal to 15 cm.Įxample 2. Solution.Perimeter of the quadrilateral ABCD = 2 cm + 6 cm + 3 cm + 4 cm Find the perimeter of below given quadrilateral. Perimeter of the quadrilateral = Length of AB + Length of BC + Length of CD + Length of ADĮxample 1. Perimeter of a quadrilateral is the sum of the length of all four sides. So, the perimeter of the square is equal to 20 cm. Solution.Perimeter of the square = 4 x Side length = 4 x 5 cm = 20 cm. We know all the sides of a square are equal.Įxample 1. Perimeter of a square is sum of all four sides. So, the perimeter of the rectangle is equal to 16 cm. Perimeter of the rectangle = 2 x (Length + Breadth) Find out the perimeter of a rectangle whose length is equal to 5 cm and breadth is equal to 3 cm. Perimeter of a rectangle = 2 x (Length + Breadth)Įxample 1. We know that opposite sides of a rectangle are equal. Perimeter of a rectangle is sum of all four sides. So, the perimeter of the triangle is 12 cm. Perimeter of the above triangle = Length of AB + Length of BC + Length of AC Find out the perimeter of the below given triangle. So, the perimeter of the triangle is 17 cm.Įxample 2. Perimeter of the triangle = Length of AB + Length of BC + Length of AC Perimeter of a triangle can be find out by adding the length of it’s three sides. Let’s find out perimeter of triangle, rectangle, square and quadrilateral. Perimeter is the sum of the lengths of the sides of any figure.
