Question

The base of a rectangle is$x+3$  and height X .What is the area?

Step-by-Step Solution

Answer

The area of the rectangle is$(x^2+3x)sq.unit$  

Step 1. Given information.

Base of the rectangle$b=x+3$

Height of the rectangle$h=x$ .

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 base and height  into the formula and find the area.

Area of the rectangle :

$\begin{array}{c}A=(x+3)x\\ =(x^2+3x)sq.unit\end{array}$

Therefore, the area of the rectangle is$(x^2+3x)sq.unit$ .
