Question

square sheet of paper has a perimeter of 40 cm what is the length of its side? also find the area of the square feet?

Answer 1

Dear Student,

Given:
Perimeter = 40 cm
​And we know, Perimeter of a square sheet = 4 x side
=> 40 = 4x side
=> side = $\frac{40}{4}$
=> side = 10 cm

And we know area of a square sheet = (side)²
= (10)²
= 100 cm²
