Question

Find the perimeter of a rectangle of which length is 5 more than the width

Answer 1

P = 4W + 10

Explanation:

Perimeter is 2 × (length + width)

let length be L and width be W

if length is 5 more than width

L = W + 5

P = 2(L + W)

P = 2(W + 5 + W)

P = 2(2W + 5)

P = 4W + 10

Answer 2

the perimeter= 10+4W.

where W= the width.

Explanation:

mathematically, perimeter (p)= 2L +2W

where L= length.and W=width

from the expression ;length is 5 more than the width

it is written as L = 5+W

substitute in the formula

P= 2(5+W)+2W

P=10+2W+2W

P=10+4W as the perimeter of the rectangle.
