A right triangle is in the diagram below. The area of the two squares is shown. What is the are of the third square? 841 ft and 400ft are given whats the third smallest square.

maybe i can

$4034.40

the perimeter of the field is the sum of the lengths of the four sides:

47 yd + 158 yd + 47 yd + 158 yd = 410 yd

the cost of 3 ft (1 yd) of fence is 3×$3.28 = $9.84.

so the cost of jake's wood perimeter fance is

(410 yd) × ($9.84 /yd) = $4034.40

thats not a system of equations, that is a solution
