Given the area of a square is 225 sq ft what is the length of each side?

each side is 15 ft

step-by-step explanation:
Area of a square = side^2
aka length * width
plug in what we know...
225 = side^2
sqrt 225 = side (via reverse PEMDAS)
side = 15 ft

38+105= 143, 39+104=143, and you will find then adding the numbers on opposite sides, moving inwards yields the answer 138 every time. because of this, you’re going to multiply 138 times the number of pairs, which is 34. therefore, 34*138= 4692(i’m sorry if it’s the wrong numbers, but it’s the right concept)
