Question

FIND THE AREA OF THE SHADED REGION FOR FOLLOWING FIGURE.​

Answer 1

100+36=136

=11.6×4

= 46.64 is perimeter

Answer 2

Answer: 120 $cm^{2}$

Step-by-step explanation: First find the area of 1 triangle

Area = $\frac{1}{2}$ x 6 x 10

Area = 3 x 10

Area = 30 $cm^{2}$

Then find the area of whole field

Area = 20 x 12

Area = 240

Then find area of 4 triangles

Area = 4 x 30

Area = 120

Area of shaded region = 240 - 120

Area of shaded region = 120 $cm^{2}$
