A tailor trims 4 feet from opposite edges from a square piece of cloth and 5 feet from the other set of opposite edges. If 120 feet of cloth remains, what was the length of a side of the original piece of cloth?
A - 12
B - 20
C - 24
D - 26
E - 40
I dont understand "from opposite edges" how exactly is it cut??
I know it isn't popular around these parts but I plugged in 20. Area equals 400. Therefore if you cut off 4 feet from each side you lose 8 total feet and therefore one side ia 12. On the other side you lose a total of 10 feet and therefore the other side is ten. L*W equals 120.
