<em>If a rectangular prism has a volume of 470.40 cm</em><span><em>³, and the length and width is equal to 6.4 and 9.8, we will find the height by using some inverse operations. We will use the variable h to represent height</em>

<em>Length x Width x Height = Volume</em>
<em>6.4 cm • 9.8 cm `• h = 470.40</em>

<em>470.40 ÷ (9.8 x 6.4)</em>
<em>     = 470.40 ÷ 62.72</em>
<em>     = 7.5</em>


<em>Check Answer:</em>
</span><em>Length x Width x Height = Volume</em>
<em>6.4 cm • 9.8 cm `• 7.5 = 470.40</em>

Ms. Gianco buys a rug that is 10 ¾ feet x 12 ½ feet. What is the area of the rug? Show your thinking with an area model and a mu
NikAS [45]

Answer:

134.375 or 134 3/8 square feet is the area of the rug

Step-by-step explanation:

In this question, we learnt someone bought rug measuring some lengths per sides were asked to help calculate the area of the rug.

Firstly, we can see that the lengths of the two sides differ? We can thus conclude that the rug is rectangular in shape.

Hence, to calculate the area of this rug, what we do is to calculate the area of the rectangle formed by the rug.

Mathematically, the area of the rug would be = l * b

According to the question, we can identify that l = 10.75 feet(3/4 = 0.75) while the b = 12.5 feet(1/2 = 0.5 feet)

Hence the area of the rug A is thus; 10.75 * 12.5 = 134.375 sq. Feet ( 0.375 = 3/8 so we can say 134 3/8 feet)
