If the sides of a square are increased by 3 m. The area becomes 64m².Find the length of a side of the original square.

Sagot :

64m² the side of each is 8, so the original size is 5 because it was increased by 3
(x+3)² = 64
x+3  = +/- √64 
But we only get the positive value since a length is never negative.
x + 3 = 8
x = 5

Therefore the original length is 5m.
