Question

the length of a rectangle is 3 more than its width if the perimeter of the rectangle is 90 cm then find the length and width of the rectangle​

Answer 1

Step-by-step explanation:

Let the breadth be x so length =3x

Perimeter=90cm

We know that perimeter of a rectangle=2(l+b)

So,Perimeter=2(x+3x)

2x+3x=90

5x=90

x=90/5

x=18cm
