Question

Find the perimeter of the rectangle shown. (HINT: Watch the units. Since your answer needs to be in meters, convert 350 cm to meters before finding the perimeter)A) 25 metersB) 768 metersC) 18 metersD) 3,150 meters

Answer 1

Given:

There are given that the rectangle whose sides are 350 cm and 9 m.

Explanation:

To find the perimeter of a rectangle, first, we need to convert 350 cm into meters.

So,

$\begin{gathered} 350cm=\frac{350}{100}m \\ =3.5m \end{gathered}$

Now,

From the formula of the perimeter of rectangle:

$Perimeter=2(l+w)$

Then,

$\begin{gathered} Perimeter=2(l+w) \\ Perimeter=2(3.5+9) \\ Perimeter=2(12.5) \\ Perimeter=25m \end{gathered}$

Final answer:

Hence, the correct option is A.
