Question 322013
Length = 6

diagnoal = 10

side = x

We need to find x using the Pythagorean Theorem.

x^2 + 6^2 = 10^2

x^2 + 36 = 100

x^2 = 100 - 36

x^2 = 64

{{{sqrt(x^2)}}} = {{{sqrt(64)}}}

x = 8

The width is 8.

Area = length times width

Area = length times width

Area = 6 times 8

Area = 48 square feet

Done!
