Question

The area of a trapezoid is 145cm2. The height is 10cm and the length of one of the parallel sides is 10cm. Find the length of the second parallel side. Express your answer as a simplified fraction or a decimal rounded to two places.

Answer 1

Answer:19.00

Step-by-step explanation:

area of any trapezoid =1/2*hieght*(sum of parallel sides)

145=1/2*10*(a+10)

145=5(a+10)

a+10=29

a=19.00
