The length of a rectangle is 7 meters longer that it’s width. What is the width of this rectangle if it’s perimeter is equal to

dolphi86 [110]

The width of rectangle is 21 meters.

Step-by-step explanation:

Given,

Perimeter of rectangle = 98 meters

Width of rectangle = w

Length of rectangle = w+7

Perimeter of rectangle = 2(Length+Width)

Perimeter = $2(w+7+w)$

$98=2(2w+7)\\98=4w+14\\98-14=4w\\84=4w\\4w=84$

Dividing both sides by 4

$\frac{4w}{4}=\frac{84}{4}\\w=21$

Width of rectangle = 21 meters

The width of rectangle is 21 meters.
