Question

The perimeter of a rectangle is 15cm if the length is 15cm,find the breath

Answer 1

If the QUESTION IS:-The length a a rectangle is 15 cm more than its width . The perimeter is 150 cm . Find the measures of length and width of the rectangle

ANSWER

Let the breadth=x

the length =x+15

given perimeter=150

we know

Perimeter of rectangle=2(l+b)

150 = 2( x+ x+15)

75=2x+15

60=2x

30=x

therefore breadth =30 cm

length =30+15=45 cm

check

150=2(45+30)

150=2(75)

150=150

LHS=RHS

hence proved.
