Plz help if correct ill give brainliest

For this, in basic terms, is asking for the two areas, of each shape, and then add those two together.

So, for the square:

A = Length • Width
A = 8•8
A = 64

Then, for the triangle:
A = 1/2 • Base • Height
A = 1/2 • 6 • 8
A = 3 • 8
A = 24

Finally:
64 + 24 = 88

The final answer is 88 ft^2

Hopefully this helped!
