Question

the perimeter of a square formed by doubling the side of the first square is 40m find side of the 1st square

Answer 1

Perimeter of the square = 40 m

Side length of the square = 40÷4 = 10 m

10 m is the length of side of the square which has been formed after doubling the side of first square.

So length of side of first square = 10÷2 = 5 m

Hence required side of the 1st square is 5 m

Hope This Helps You!

Answer 2

Hi !

GIven ,
Perimeter of  square = 40 m

Side  = 40/4
  = 10 m

The length of side of the square which has been formed after doubling the side of first square , is 10 m .
Length of side of first square would be half of the length of the other square.

Length of side of first square = 10/2 = 5 m
