Question

7. Find the area of the shaded region in the following figures.
​

Answer 1

Step-by-step explanation:

1.) Rectangle:

Given

there are 4 identical triangles, so we will find the area of 1 and multiply it by 4

Length Of Whole Triangle = 20m

Breadth Of Whole Triangle = 13m

there is a 2m strip from each side

if we subtract 2m strip from each side

13 - 2 = 11m

20 - 2 = 18m

so,

area of rectangle = Length × Breadth

= 11 × 18

= 198 sq. m

now,

198 ÷ 4

= 49.5 sq. m

area of each rectangle = 49.5 sq. m
