1.	the length of a rectangle is 5 metres less than twice the breadth.if the perimeter is 50 metres find length and breadth of the rectangle
Answer» the length is 5-2x , breadth we SAY x =x perimeter=50m perimeter of a rectangle = 2(l+b) →50=2(5-2x+x) → 50= 2(5-x) → 50 = 10 - 2x → 50-10 = -2x → 40= -2x → x= -40/2 → x = -20

the length of a rectangle is 5 metres less than twice the breadth.if the perimeter is 50 metres find length and breadth of the rectangle

Answer»

the length is 5-2x ,

breadth we SAY x =x

perimeter=50m

perimeter of a rectangle = 2(l+b)

→50=2(5-2x+x)

→ 50= 2(5-x)

→ 50 = 10 - 2x

→ 50-10 = -2x

→ 40= -2x

→ x= -40/2

→ x = -20
