Question

The length of a rectangle is 5 metres less than twice the breadth. If the perimeter is 50
metres, find the length and breadth of the rectangle.​

Answer 1

Answer:

the length of the rectangle (l)=10 meters

the breadth of the rectangle (b)=15 meters

Step-by-step explanation:

the breadth of the rectangle(b)=2x

the length of the rectangle (l)=2x-5

the formula for the perimeter of the rectangle =2(l+b)

the perimeter of the rectangle=50meters

2(2x-5+2x)=50

2(4x-5)=50

8x-10=50

8x=50+10

8x=60

x=60/8

x=15/2

the breadth of the rectangle (b)=2x=2(15/2)=15meters.

the length of the rectangle (l)=2x-5=2(15/2)-5= 15-5=10 meters.

I Hope it helps you ☺️
