Question

The length of a rectangle is 5cm more than width. Find expression fo the perimeter of the rectangle in terms of the w

Answer 1

Answer:

Perimeter $=4w+10$

Step-by-step explanation:

Let $w$ = width of the rectangle.

From the information "length of a rectangle is 5cm more than width", we can write:

Length = $w+5$

- - - -

Perimeter $= 2l+2w$ (formula for the perimeter of a rectangle)

$=2(w+5)+2w$

$=2w+10 + 2w$

$=4w+10$

∴ The expression of the perimeter of the rectangle in terms of $w$ is $4w+10$.

Hope this helps :)
