Chapter R1, Problem 1E

To determine

The area and the perimeter of the rectangle.

Answer to Problem 1E

Solution: Area of rectangle = $105{\text{ft}}^2$ , Perimeter of rectangle = $44\text{ft}$ .

Explanation of Solution

Explanation:Given: Width of rectangle = $7$ ft, Length of rectangle = $15$ ft.

Formula used:

1. Area of the rectangle with length L and width W is given as
$Area=L\times W$
2. Perimeter of the rectangle with length L and width W is given as
$Perimeter=2(L+W)$

Calculation:$\begin{array}{l}Area=L\times W\\ =7\text{ft}\times 15\text{ft}\\ =105{\text{ft}}^2\end{array}$

  $\begin{array}{l}Perimeter=2(L+W)\\ =2(15+7)\text{ft}\\ =2\times 22\text{ft}\\ =44\text{ft}\end{array}$

Conclusion: The area and perimeter of the rectangle are $105{\text{ft}}^2$ and $44\text{ft}$ respectively.
