Question

the length of a rectangle is 25 cm and its breadth is 15 CM if the perimeter of a square is same as the perimeter of this rectangle then find the area of the square​

Answer 1

$\huge\underline\mathcal{Given}$

Length of rectangle = 25cm

Breadth of rectangle = 15cm

Perimeter of square = perimeter of rectangle

$\huge\underline\mathcal{Formulae}$

${perimeter of square= 4 × side}$

${perimeter of rectangle= 2(l+b)}$

${Area of square= side × side}$

$\huge\underline\mathcal{Solution}$

Perimeter of square = perimeter of rectangle

4×side = 2(l+b)

4×side = 2(25+15)

4×side= 2×40

4×side = 80

side = 80/4

side = 20cm

Area of square = side × side

= 20× 20

= 400cm²
