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
