Question

A side of a square increased by 30% what is the increase in its area

Answer 1

Answer:

Step-by-step explanation:

let the side of a square = 100 units

then the area of a square =  100 x 100 = 10000 sq. units

if a side of a square increased by 30%

           then a side of a square = 100 + 30 = 130

so, new increase area of a square = 130 x 130 = 16900 sq. units

so increase in area = 16900 - 10000

                                =  6900 units
