Question

a rectangle has a length of 11 feet and the perimeter of 38 feet. what the width in feet of the rectangle

Answer 1

If p= 38
You need four sides to equal that
11 is length so that means two sides are 11
11+11= 22
So that means you need two more equal numbers that will finish making up the 22
38-22= 16
But two sides make up 16
16 divides by 2 is 8
So THE WIDTH IS 8

Answer 2

Using the formula for perimeter of rectangle, the width of the rectangle is 8 feet.

What is rectangle?

"A rectangle is a quadrilateral in which all the angles are equal (90°) and the opposite sides are equal and parallel."

What is perimeter?

"Perimeter is the distance around the edge of a two-dimensional shape"

Formula to calculate the perimeter of rectangle:

$P=2(l+w)$

where, $P$ is the perimeter of rectangle

$l$ represents the length of the rectangle

$w$ represents the width of the rectangle

For given question,

length of a rectangle ($l$) = 11 feet

perimeter of a rectangle ($P$) = 38 feet

Using the formula for perimeter of rectangle,

$P=2(l+w)$

⇒ $38=2(11+w)$

⇒ $19=11+w$

⇒ $19-11=w$

⇒ $w=8$ feet

Hence the width of a rectangle is 8 feet.
