Chapter 11: Q13. (page 425)

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

Short Answer

Expert verified

The area of the rectangle is $(x^{2} + 3 x) s q . u n i t$

Step by step solution

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 :

$\begin{matrix} A = (x + 3) x \\ = (x^{2} + 3 x) s q . u n i t \end{matrix}$

Therefore, the area of the rectangle is $(x^{2} + 3 x) s q . u n i t$ .
