Question

Area of a square is 169 cm2.If the area of the square isincreased by 69%,by what percentage does the edge of the square increased?

Answer 1

Answer:

30%

Step-by-step explanation:

Area = 169 cm^2

Side = 13 cm

Area increased by 69 % =  (69/100)*169 =  116.61  cm^2

Increased Area = 169 + 116.61 = 285.61  cm^2

Increased side = √285.61  =  16.9 cm

Increase in side = 16.9 - 13 = 3.9 cm

% increase in side = (3.9/13)*100 = 30%
