Question

The perimeter of a rectangle is 78 cm. Its length is 3cm more than twice its breadth.Find the length and breadth of the rectangle.

Answer 1

Step-by-step explanation:

Let the breadth bex Let the length be 2x +3

A/Q

78=2,{x + 2x+3) 78=2x+4x+6

78=6x+6

78-6=6x

72=6x

x=72/6

x=12

breadth =12 length =2xx+3 =2x12+3

=24+3=27

Answer 2

Step-by-step explanation:

let the breadth of rectangle be b.

length of rectangle=2b+3

perimeter of rectangle=78

2(l+b)=78

2(2b+3+b)=78

3b+3=39

3b=36

b=12

l=24+3

l=27
