The side length of a square is 5 cm. The area increases by 44%. What is the new side length of the square? A) 6 cm B) 7.2 cm C) 8 cm D) 18 cm
The area of the original square is 5 cm * 5 cm = <<5*5=25>>25 cm²
The area increased by 44%, so the new area is 25 cm² + 25 cm² * 44% = 25 cm² + 11 cm² = <<25+11=36>>36 cm²
The new side length is the square root of the new area, so the square root of 36 cm² = 6 cm
The answer is choice A) 6 cm.
