Chapter 8.4, Problem 28E

(a)

To determine

To find: The area of garden

Answer to Problem 28E

The areas of garden is $72{\text{ft}}^2$ .

Explanation of Solution

Given information: The following figure is been given:

  

Formula used: $A=b\times h$

Calculation: The area of the garden will be:

  $\begin{array}{l}A=12\left(6\right)\\ \therefore A=72{\text{ft}}^2\end{array}$

(b)

To determine

To find: The number of Zucchini plants that you can plant.

Answer to Problem 28E

The number of plant is 8.

Explanation of Solution

Given information: Each plant of Zucchini requires $9{\text{ft}}^2$ .

The following figure is been given:

  

Calculation: Since each plant take $9{\text{ft}}^2$ and total area of the garden is $72{\text{ft}}^2$ .

Hence,

  $\frac{72{\text{ft}}^2}{9{\text{ft}}^2}=8$

(c)

To determine

To find: The number of each vegetable that can you plant in the area $TUVW$ .

Answer to Problem 28E

The numbers of each plant that can be planted in area $TUVW$ are $36$ for Lettuce and $7$ for Zucchini.

Explanation of Solution

Given information: The following figure is been given:

  

Calculation:

Area for Lettuce $=9{\text{ft}}^2$

Hence the number of the Lettuce,

  $\frac{9{\text{ft}}^2}{1}\times \frac{4}{1{\text{ft}}^{\text{2}}}=36$

Similarly for Zucchini $=72{\text{ft}}^2-9{\text{ft}}^2=63{\text{ft}}^2$

  $\frac{63{\text{ft}}^2}{1}\times \frac{1}{9{\text{ft}}^{\text{2}}}=7$
