The area of a rectangle is 2- 3/4 inch. ^2 If the length of the rectangle is 1/2 inch, what is the measurement of the width?
Lelechka [254]

Answer:

The width of the rectangle = 1.15 inches

Step-by-step explanation:

<u><em>Explanation:-</em></u>

Given that the length of the rectangle = \frac{1}{2} inch

The area of the rectangle = \frac{2.3}{4} inch²

We have to find the width of the rectangle

The area of the rectangle = length × width

                                  \frac{2.3}{4} = \frac{1}{2} X width

                    ⇒     2 × 2.3 = 4× width

                   ⇒      4.6 = 4 w

                  ⇒      w = 1.15 inches

<u><em>Final answer:-</em></u>

The width of the rectangle = 1.15 inches
