Question

The lenth of a rectangle is 5more than its breadth. So express its perimeter in the form of polynomials

Answer 1

hello..

L̳e̳t̳ b̳r̳e̳a̳d̳t̳h̳ b̳e̳ x̳
L̳e̳n̳g̳t̳h̳ b̳e̳ ( x̳+5)

S̳o̳ p̳e̳r̳i̳m̳e̳t̳e̳r̳ = 2(l̳ +b̳)

2 ( x̳+x̳+5)

2(2x̳ +5)
= 4x+10
thank you

Answer 2

Let the length be 'l'

so its breadth is 'l - 5'

Formula for perimeter = 2 ( length + breadth )

Here,

Perimeter = ( 2 ( l + l - 5 ) = 2(2l - 5 ) = 4l - 20

Answer is '4l - 20'
