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.

Answer 2

Step-by-step explanation:

Perimeter of Rectangle =2( l+b)

Let the breadth be x

then l= 15+x

150= 2× ( 15+x+x)

150 = 2(15+2x)

= 30+ 4x

150- 30= 4x

120= 4x

X=™120÷4

x=™30

X, Breadth is 30cm

Length is 30+15= 45cm
