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
