Chapter 11: Q8. (page 426)

The base of a rectangle is $4 k - 1$ and height $k + 2$ . What is the area?

Short Answer

Expert verified

The area of the rectangle is $(4 k^{2} + 7 k - 2) s q . u n i t$

Step by step solution

Step 1. Given information.

Base of the rectangle $b = 4 k - 1$

Height of the rectangle $h = k + 2$ .

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 base and height into the formula and find the area.

Area of the rectangle :

$\begin{matrix} A = (4 k - 1) (k + 2) \\ = (4 k^{2} + 7 k - 2) s q . u n i t \end{matrix}$

Therefore, the area of the rectangle $(4 k^{2} + 7 k - 2) s q . u n i t$ is .
