Question

The width of a rectangle is $45$centimeters. The area is $2,700$square centimeters. What is the length?

Short answer

The length of the rectangle is $60cm$.

Step-by-step solution

Step 1. Given information.

Consider the given question,

Area of the given rectangle is $2700$square centimeters.

Width of the given rectangle is $45$ centimeters.

Step 2. Find the length.

We know the formula of the area of the rectangle is given below,

$A=length\times width......\left(i\right)$

Substitute the given values in equation (i),

$$\begin{gathered} 2700=length\times 45 \\ length=\frac{2700}{45} \\ length=60cm \end{gathered}$$

Step 3. Check the answer.

Substitute the values of length and width in equation (i),

$$\begin{gathered} A=60\times 45 \\ A=2700c{m}^2 \end{gathered}$$

Hence, the value of the length obtained is correct.
