Mario is constructing a wall around a rectangular area which will cover a maximum of 60 square feet. The length of the wall will

Feliz [49]

Answer:

$W \le 6$

Step-by-step explanation:

Given

$Area = 60ft^2\ (max)$

$Length = 10ft$

Required

Represent the width as an inequality

First, we represent the area as an inequality.

$Area = 60ft^2\ (max)$

max as used above means less than or equal to.

So, we have:

$Area \le 60$

The area of a rectangle is:

$Area = L * W$

So, we have:

$L * W \le 60$

Substitute 10 for L

$10 * W \le 60$

Divide both sides by 10

$\frac{10 * W}{10} \le \frac{60}{10}$

$W \le \frac{60}{10}$

$W \le 6$

Answer:

B. $33.7 mm; 54mm^2$

Step-by-step explanation:

<em><u>To find the perimeter, use the formula:</u></em>

P = a + b + c

P = 12 + 12 + 9.7

P = 33.7

<em><u>To find area, use the formula:</u></em>

A = $\frac{1}{2} bh$

A = $\frac{1}{2} (12)(9)$

A = $\frac{1}{2} (108)$

A = 54
