Question

The side of a square field is 16m.what will be increase in its area if each of its sides is increased by 4m?

Answer 1

It will 16 times increases

Answer 2

Answer:

144 sq.m.

Step-by-step explanation:

Side of square = 16m

Area of square = $(Side)^2$

                         = $16^2$

                         = $256 m^2$

Since each of its sides is increased by 4 m

So, new side = 16 m+4 m = 20 m

Area of new square  = $20^2$

                                  = $400 m^2$

Increase in area = Area of new square - area of square

                            = $400 m^2 - 256 m^2$

                            = $144 m^2$

Hence the increase in area is 144 sq.m.
