Question

2) Perimeter of a square and a rectangle is the same. If a side of the square is 15 cm and
one side of the rectangle is 18 cm, find the area of the rectangle.​

Answer 1

Answer:

Perimeter of square = perimeter of rectangle

Perimeter of square =4*side=60 cm

Then the perimeter of rectangle will be 60 cm

But perimeter of rectangle=2(l+b)

60=2(18+b)

60=36+2b

2b=24

b=12 cm

Area of rectangle=l*b

=18*12=216 cm²
