AREA=(S1+S2)/2*16
224=[(20+S2)/2]*16
224=[20+S2)*8
224=160+8*S2
224-160=8*S2
8*S2=64
S2=64/8
S2=8m THE LENGTH OF THE SECOND SIDE.
PROOF
224=[(20+8)2]*16
224=[(28/2]*16
224=14*16
224=224

Rose�s garden is in the shape of a trapezoid. If the height of the trapezoid
is 16 m, one base is 20 m, and the area is 224 m2, find the length of the other base.
The formula for the area of a trapezoid is: where is one base and is the other base.
We know that , , and .
So, plug these numbers into the area formula and .
Or, .
So, or . So, .
Let's verify that .
