Question

length of the rectangle is 5 units more than its breadth. Express its perimeter in polynomial form.​

Answer 1

Answer:

length =x+5 and let breadth be x cm

Perimeter =(x+5)+x

=2x+5

therfore perimeter=f(x)= 2x+5

Answer 2

Answer:

length (l)= 5+b

breadth (b) = b

perimeter = ?

p = 2(l+b )

p= 2(5+b+b)

p= 10 2(2b)

p= 10 +4b

therefore perimeter = 10+4b
