where r is the radius

C = 2 * pi * 21

Answer:

96 inch²

Step-by-step explanation:

there are 2 shapes,

1. a square

2. a triangle

lets find the area of the square first,

<u>AREA = SIDE × SIDE</u>

= 8 × 8

= 64 inch²

now, area of triangle ,

$area \: = \frac{1}{2} \times base \: \times height \:$

$= \frac{1}{2} \times 8 \times 8 \\ = \frac{1}{2} \times 64 \\ = 32 \: {inch}^{2}$

so, total area is :

area of square + area of triangle

= 64 + 32

= 96 inch²
