The composite figure is made up of a parallelogram and a rectangle. Find the area.
MAXImum [283]

Answer: A. 76 sq. units


Step-by-step explanation:

1. You can use the following formula for calcualte the area of the parallelogram:

A_p=b_p*h_p

Where b_p is the base and  h_p is the height of the parallelogram

b_p=14units-3units-3units=8units and h_p=6units

2. The formula for calculate the area of a rectangle is:

A_r=b_r*h_r

Where  b_r is the base and  h_r is the height of the rectanngle.

b_r=14units  and h_r=2units  

3. Then, the area of the figure is the sum of the area of the parallelogram and the area of the rectangle:

A_f=(8units*6units)+(14units*2units)=76units^{2}
