Question

If side of the square triples its initial side,then perimeter equals the area of new square ,find the side of square.

Answer 1

initially say side of square is 'a'm then after tripling it become 3a.perimeter=4×3a=a^2
which gives side of new square = 12m

Answer 2

12 is the side of the square.

Given :  

The side of the square is tripled

To find :

Side of the new square

Solution :

Since the side of the square is tripled its initial side,

Let a be the initial side of the square

After tripling, it becomes $3a.$

By formula, Perimeter of the square $= 4a$

The new perimeter becomes $= 4 \times 3 a = 12a$

Hence the side of the new square = 12.
