Q4. - Geometry

Question

The height of a rectangle is 8cm and area is$120c{m}^2$  .What is the base?

Step-by-Step Solution

Answer

The base of the rectangle is  15cm

Step 1. Given information.

Height of the rectangle$h=8cm$

Area of the rectangle$A=120c{m}^2$ .

Step 2. Concept Used.

If b is the base of the reactangle and h is the height of the rectangle.

Then, the   area of the rectangle is $A=b\times h$

Step 3. Let’s calculate the area of the rectangle.

Put the value of height and area into the formula and find the base.

Area of the rectangle :

$\begin{array}{c}120=b\times 8\\ b=\frac{120}{8}\\ =15cm\end{array}$

Therefore, the base of the rectangle is15cm .
