What is the area of this figure? 49.5 in² 66.5 in² 84 in² 91 in²

zubka84 [21]

The given figure can be divided in two parts 1) Square with side 7 in 2) A right triangle with base 12 in and height 7 in.

1) Area of square = $side^{2}$

Side of the square is 7 in.

Area = $7^{2} =49in^{2}$

2) Area of triangle = $\frac{1}{2} .base . height$

Area of triangle = $\frac{1}{2} (12)(7) =42in^{2}$

Area of polygon= Area of square+ Area of triangle

Area of polygon = 49+42 =91 square in.

Area = $91in^{2}$
