Question

The area of a rectangle is 18.5 square centimeters. The length is 2.5 centimeters. What is the width?

Answer 1

To find the width of the rectangle, you can follow the steps.

Step 1: Write the formula for the Area of a rectangle (A).

The area of a rectangle (A) is the product of the length (l) and the width (w).

That means,

`A=l\cdot w`

Step 2: Substitute the values that you know in the formula.

It is known that

A = 18.5 cm².

l = 2.5 cm.

Then,

`18.5=2.5\cdot w`

Step 3: Isolate w.

To isolate w, divide both sides of the equation by 2.5.

`\begin{gathered} (18.5)/(2.5)=(2.5)/(2.5)\cdot w \\ 7.4=1w \\ 7.4=w \end{gathered}`

Answer: The width is 7.4 cm.
