Question

The perimeter of a rectangle is 250 m. If the length of the rectangle is 5 m more than

twice the breadth, find the length and breadth of the rectangle.​

Answer 1

Answer:

pls mark it as brainliest

Explanation:

Let the breadth of the rectangle be xcm

Then it's length=x+5cm

Perimeter=2(length+breadth)

⇒70=2(x+(x+5))

⇒

70

=2x+5

⇒2x+5=35

⇒2x=35−5=30

⇒x=

30

=15cm

Breadth=x=15cm and length=x+5=15+5=20cm

Answer 2

Explanation:

let the length be 5x

breadth be x

perimeter=2(1+b)

250 = 2(5x+x)

250

length=5x

= 5x2.83

=14.15

breadth=x

= 2.83
