Question

10 mThe area of this rectangle is 30 m2.Which is the perimeter of the rectangle?O A 3 m0B. 13 mOC 20 mD. 26 mE. 30 m

Answer 1

Explanation:

The area of a rectangle is represented by the following expression:

`\text{Area}=\text{length}\cdot\text{width}`

Then, if we have that the area is 30 square meters and the length is 10 meters.

To determine the perimeter, we need to know the width, solve for the variable width:

`\begin{gathered} 30=10\cdot\text{width} \\ \text{width}=(30)/(10) \\ \text{width}=3\text{ meters} \end{gathered}`

Now, the perimeter of a rectangle is defined by the following expression:

`\text{Perimeter}=2\cdot\text{width}+2\cdot\text{length}`

Therefore, the perimeter of this rectangle would be:
