Question

The perimeter of a rectangular garden is 43.8 feet. It's length is 12.4 feet. What is its width?

Answer 1

9.5
If you add 12.4 plus 12.4 you get 24.8 then you do 43.8 minus 24.8 and you get 19 and 19 divided by 2 is 9.5
9.5+9.5+12.4+12.4=43.8

Answer 2

The width of the rectangular garden is 9.5 feet

From the question,

We are to determine the width of a rectangular garden whose perimeter is 43.8 feet and length is 12.4 feet

We will use the formula for calculating the perimeter of a rectangle

$P = 2(l + w)$

Where $P$ is the perimeter

$l$ is the length

and  $w$is the width

From the question

$P = 43.8\ feet$

$l = 12.4 \ feet$

Now, we will put the above parameters into the formula to determine w

That is

$P = 2(l + w)$ becomes

$43.8 = 2( 12.4 + w)$

Then,

$43.8 = 24.8 + 2w$

$2w = 43.8 - 24.8$

$2w = 19$

Now, divide both sides by 2

$\frac{2w}{2}=\frac{19}{2}$

w = 9.5 feet

Hence, the width of the rectangular garden is 9.5 feet
