Question

A trapezoid has bases that measure 9 cm and 5 cm. The height of the figure is 4 cm . What is the area of the trapezoid ?

Answer 1

area = 28 cm²

the area of a trapezoid =
`(h)/(2)` ( a + b )

where h is the height and a, b the bases

here h = 4, a = 9 and b = 5

area =
`(4)/(2)` ( 9 + 5 ) = 2( 14 ) = 28 cm²

Answer 2

To find the area of a trapezoid, add the 2 bases together, divide that by 2, then multiply that by the height:

9 +5 = 14, 14/2 = 7, 7 *4 = 28

The area is 28 square cm.
