Question

length and breadth of a rectangle are 40m and 30m respectively,Id it's perimeter is equal to the perimeter of a square ,find the side of the square.​

Answer 1

Step-by-step explanation:

Given,

Length = 40m

Breadth = 30m

Perimeter of rectangle = Perimeter of Square

We know that,

Perimeter of rectangle = 2(l+b)

= 2 (40 + 30)

= 2 x 70

= 140cm

Now we know that perimeter of rectangle = perimeter of square. So,

Perimeter of square = 4 x each side = 140cm

Let each side be 'x', so

4x = 140cm

x = 140/4

x = 35cm

Therefore the side of the square = 35cm
