Cross section

The cross-section ABCD of a swimming pool is a trapezium. Its width AB=14 meters, depth at the shallow end is 1.5 meters, and at the deep end is 8 meters. Find the area of the cross-section.

Correct answer:

A =  66.5 m2

Step-by-step explanation:

a=14 m h1=1.5 m h2=8 m h=(h1+h2)/2=(1.5+8)/2=419=4.75 m A=a h=a 419=14 4.75=66.5 m2
