Question

thevsides of a square are increased by 50%find the percentage increase in its area
​

Answer 1

Answer:

125% increase

Step-by-step explanation:

Let the side of the square be x.

Area of square = x²

Increase in side = 50%

New side = 150% of x = 1.5x

New area of square = (1.5x)² = 2.25x²

Increase in area = 2.25x² - x² = 1.25x²

Percentage increase = 1.25x²/x² × 100 = 125%
