Question

The length of a rectangle is 15 cm more than breadth lts perimeter is 150cm find the length and breadth?

Answer 1

Answer:

let the breadth of rectangle be x cm

then it's length is =x+15 cm

now,

2(l+b) =150 cm

(x+15+x) =150/2

(2x + 15)=75

2x = 75-15

2x=60

x =30cm

hence breadth =30cm

and length is (x+15)= 30+15

=45

Answer 2

Step-by-step explanation:

Let the breadth of the rectangle be x

The length of the rectangle = 15+x

Perimeter of rectangle = 2(l+b)

150 = 2(15+x+x)

150 = 2(15+2x)

150 = 30+4x

150 - 30 = 4x

120 = 4x

120/4 = x

x = 30

The breadth of rectangle = 30

The length of the rectangle = 15 + 30

= 45.
