Chapter 11: Q6. (page 425)

The base of a rectangle is 8cmand height 3cm.What is the area?

Short Answer

Expert verified

The area of the rectangle is $24 c m^{2}$

Step by step solution

01

Step 1. Given information.

Base of the rectangle $b = 8 c m$

Height of the rectangle $h = 3 c m$ .

02

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 $A = b \times h$

03

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

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

Area of the rectangle :

$\begin{matrix} A = 8 \times 3 \\ = 24 c m^{2} \end{matrix}$

Therefore, the area of the rectangle is $24 c m^{2}$ .
