Question

the length and breadth of rectangle are 40 m and 30 M respectively if its perimeter is equal to the perimeter of a square find the side of the square

Answer 1

Answer:

35 M

Step-by-step explanation:

Perimeter of rectangle= 2 ×( l+ b)

=2 × (40+30)

=2×70

=140m

Perimeter of square = Perimeter of rectangle

4a= 140

a= 35 m

Answer 2

The side of the square is 35 m.

Step-by-step explanation:

The formula to compute the perimeter of a rectangle is, P = 2 (l + b).

The formula to compute the perimeter of a square is, P = 4a.

Given:

l = 40 m

b = 30 m

Compute the value of a if the perimeter of a rectangle is same as that of square:

$2(l+b)=4a\\2(40+30)=4a\\2\times 70=4a\\140=4a\\a=\frac{140}{4}\\a=35$

Thus, the side of the square is 35 m.
