Question

a square and a rectangle have the same perimeter . if the length and the breadth of the rectangle are 55cm and 35cm find the side of the square.​

Answer 1

Answer:

45 cm

Step-by-step explanation:

P of square = P of rectangle

4 * side = 2(l+b)

4 * side = 2(55+35)cm

4 * side = 2 * 90cm

side = $\frac{180}{4}$cm

side of square = 45 cm

Answer 2

Question ::-

A square and a rectangle have the same perimeter . if the length and the breadth of the rectangle are 55cm and 35cm find the side of the square.

__________________________________

Answer ::-

Breadth of Rectangle = 35 cm

Length of Rectangle = 55 cm

To find the side of square we have to find the perimeter of rectangle.

Perimeter of Rectangle = 2 × ( l + b )

Perimeter of Rectangle = 2 × ( 55 + 35 )

Perimeter of Rectangle = 2 × 90

Perimeter of Rectangle = 180 cm

_________________________________

Now, We know perimeter of square is 180 cm.

Now, we have to side of the square.

Let the Side of Square be x

Therefore,

X = $\LARGE\frac{Perimeter}{4}$

X = $\LARGE\frac{180}{4}$

X = 45 cm

Therefore, Side of the Square = 45 cm.
