Chapter 11: Q9. (page 425)

The area of a rectangle is $55 c m^{2}$ and height 5cm.What is the base?

Short Answer

Expert verified

The base of the rectangle is 11cm

Step by step solution

Step 1. Given information.

Height of the rectangle $h = 5 c m$

Area of the rectangle $A = 55 c m^{2}$ .

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 area and height into the formula and find the base.

Area of the rectangle :

$\begin{matrix} 55 = b \times 5 \\ b = \frac{55}{5} \\ = 11 c m \end{matrix}$

Therefore, the base of the rectangle is11cm .
