Question

Eli is building a stage, which is shaped like a trapezoid. The bases are 7.8 and 5 yards, and the height

is 7 yards. How many square yards large is the stage?

Answer 1

44.8 square yards

Explanation:

Area of trapezoid:

a = 7.8 yds

b = 5 yds

h = 7 yds

`\sf \boxed{\bf Area \ of \ trapezoid = ((a +b)*h)/(2)}`

Here, a and b are the parallel lines and h is the height between the parallel lines.

`\sf = ((7.8+5)*7)/(2)\\\\= (12.8*7)/(2)\\\\=6.4*7\\\\=44.8 \ square \ yards`
