Tge area of a trapezoid can be found using the formula 1/2 (B + b)h. You are the cheif at a company that builds trapezoidally shaped pools. You need to create a pool cover that will cover this shape pool. You know that the (B) Base equals 5' and the (b) base equals 10'. The (h) height from base to base equals 12'. How much area do you need to cover?

1/2 (5+10) 12
1/2 (15) 12
15/2 * 12 = 15 * 6
6 * 15 = 90

Area=1/2(B+b)h
=1/2(5+10)12
=1/2*15*12
= 6*15
= 90

How much area to cover? Easy...the entire pool. Just get the huge roll and bring it to the house and start unrolling and one end of the pool and cut when you get to the end of the pool. No need for the Math stuff.

1/2 (B+b)h
1/2(5'+10')12'
1/2(15')12'
1/2 180sqft
90sqft total area to cover

1/2(B+b)h=area
1/2(5+10)12=area
1/2(15)12=area
1/2(180)=area
90inches squared=area
