A trapezoid with a height of 5 ft has bases of length 20 ft and 12 ft. Find the area of the trapezoid. ?

Question

A) 80 sq. ft

B) 160 sq. ft

C) 40 sq. ft

D) 1200 sq. ft

Thanks so much in advance for all the help!

Answer 1

The answer is:

A) 80 sq. ft

The two people above gave the correct explanation so I won't write this out again.

Answer 2

Use the formula for trapezoid area:

A = 1/2 (h)(a+b)

A = 1/2(5)(20+12)

A = 80

Answer 3

Area of trapezoid = (b1 + b2)h/2, where b1 and b2 are the bases and h is the height

(20 + 12)5/2

32(5)/2

16(5)

80

A.) 80 sq. ft. <===ANSWER

Answer 4

Thus, if a and b are the two parallel sides and h is the distance (height) between the parallels, the area formula is as follows:

    A= h [ (a+b)/2]

A = (5) [ (20+12)/2]

A = 5 (16)

A = 80
