Question

if the parameter of sqaure is 42 cm then find its area​

Answer 1

Perimeter of square = 42cm

We know, Perimeter = 4×side

= 4×side = 42

Side = 42/4= 10.5 cm.

Now, Area of square = side² or side×side

So, now side =10.5cm

Therefore, Area = 10.5×10.5 = 110.25 cm² Answer

Hence, Area of square is 110.25 cm²
