Question

The length of each side of a square is $30cm$, and the length and breadth of a rectangle are $35cm$ and $20cm$ respectively. Find the difference between the perimeters of the rectangle and square .

Answer 1

Step 1: Find the perimeter of square and rectangle .

Perimeter of square $=$ $4\times side$

$=4\times 30$

$=120cm$

Perimeter of rectangle $=$ $2(length+breadth)$

$=2(35+20)$

$=2\left(55\right)$

$=110cm$

Step 2: Find the difference between the perimeter of a square and a rectangle

$\therefore$ the difference between the perimeters $=$ Perimeter of the square $-$ Perimeter of the rectangle

$=120-110$

$=10cm$

Therefore, the difference between the perimeter of square and rectangle is $10cm$ .

Hence, the difference between the perimeter of square and rectangle is $10cm$.
