Question

The formula for the area of a trapezoid is a=1/2h(b1+b2) are the are the length of the bases, and is the height, to answer the question. How many square feet of grass are there on a trapezoidal field with a height of 75 ft and bases of 125 ft and 81 ft?

Answer 1

A=1/2*75*(125+81)
a=1/2*75*206
a=77.25 sq ft

Answer 2

$a= \frac{1}{2} *75(125+81)$
$a= \frac{1}{2}*75(206)$
$a= \frac{1}{2}*15,450$
$a= 7725$
There's $7725ft^{2}$
