Question

What is the area of the triangle pictured?

A. 612 in2
B. 540 in2
C. 555 in2
D. 531 in2

Answer 1

D. 531
`in^(2)`

Explanation:

I suppose these are rectangles and not triangles.

Area of Rectangle = Length x Breadth

Area of Large Rectangle = 21 x 18

= 378
`in^(2)`

Area of Small Rectangle = 17 x 9

= 153
`in^(2)`

Total Area = Area of Large Rectangle + Area of Small Rectangle

= 378 + 153

= 531
`in^(2)`
