Chapter 11: Q4. (page 426)

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

Short Answer

Expert verified

The base of the rectangle is 15cm

Step by step solution

Step 1. Given information.

Height of the rectangle $h = 8 c m$

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

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 :

$\begin{matrix} 120 = b \times 8 \\ b = \frac{120}{8} \\ = 15 c m \end{matrix}$

Therefore, the base of the rectangle is15cm .
