Answer: Choice B) 50 square units

Work Shown:

A = h*(b1+b2)/2

A = 5*(12+8)/2

A = 5*(20)/2

A = 100/2

A = 50 square units (choice B)

Notice how the b1 and b2 are the parallel bases, while the height h = 5 is perpendicular to both of these bases.

Answer: 50m²

Explanation:

Area = (a+b)/2 ×h

Area = (12+8)/2 × 5

Area = 10 × 5

Area 50m²
