area = 28 cm²
the area of a trapezoid = ( a + b )
where h is the height and a, b the bases
here h = 4, a = 9 and b = 5
area = ( 9 + 5 ) = 2( 14 ) = 28 cm²
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.
