Question

if the perimeter of a rectangle is 150.the length of the rectangle is 15cm more than. find length

​

Answer 1

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

Answer 2

Step-by-step explanation:

hi dear,

perimeter of rectangle = 150. (given)

2 (l+b) = 150

2 (15+ b) = 150

30 + b = 150

b = 150 - 30

b = 120

ans is 120
