hope this helps, back to my hole i go
Actual = 6 feet.
Measure = 5.49 feet
Error = 6 - 5.49 = 0.51
% Error = (Error / Actual) * 100%
= 0.51/6 * 100% = 8.5%
So perimeter is equal to 2 lengths and 2 width so the equation would be P=2L+2W. you know width so you plug in 5 for W then solve for L and you should get L=3
(not sure if this is right but)
x (to the 2nd power) + y (to the 2nd power) = cos (90) (to the 2nd power)
