Question

Find the area 20 points!

Answer 1

132

Explanation:

First calculate the area of the triangle, Triangle area formula is 1/2 B x H meaning we'd have to do 4 x 12 which gives us 48. Then we half 48 and get 24. We then calculate the area of the rectangle which is L x W so we do 9x 12 and get 108 we add the two numbers and get 132.

Answer 2

`A_(\triangle)=(1)/(2)\cdot 12\text{ in}\cdot 4\text{ in}=24\text{ in}^2\\\\A_(\square)=12\text{ in}\cdot 9\text{ in}=108\text{ in}^2\\\\A_{\text{Figure}}=A_(\triangle)+A_(\square)=24\text{ in}^2+108\text{ in}^2=132\text{ in}^2`
