A = 180 yd²

Step-by-step explanation:

We have the rectangle 15yd × 7yd and the parallelogram with base b = 15yd and the height h = 5yd.

Area formulas:

rectangle: A = lw    (l - length, w - width)

parallelogram: A = bh    (b - base, h - height).

RECTANGLE:

l = 15yd, w = 7yd. Substitute:

A = (15)(7) = 105 yd²

PARALLELOGRAM:

b = 15yd, h = 5yd. Substitute:

A = (15)(5) = 75 yd²

The area of the area of given figure:

A = 105 yd² + 75 yd² = 180 yd²
