18 yards and 22 yards are the length of trapezoid.
Trapezoids are quadrilaterals that have two parallel sides and two non-parallel sides
Given,
shorter base to be 3 yards greater than the height
b₁=h+3
longer base to be 7 yards greater than the height.
b₂=h+7
Area of trapezoid=1/2(b₁+b₂)h
150=1/2(h+3+h+7)h
150=(2h+10)h/2
150=2h²+10h/2
150=2h²+5h
h²+5h-150=0
h²+15h-10h-150=0
h(h+15)-10(h+15)=0
(h-10)(h+15)=0
h=10 or h-15
h value should be positive.
So b₁=h+3=15+3=18
b₂=h+7=15+7=22
Hence the bases be 18 yards and 22 yards.
