Q9. - Geometry

Question

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

Step-by-Step Solution

Answer

The base of the rectangle is  11cm

Step 1. Given information.

Height of the rectangle$h=5cm$

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

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 :

$\begin{array}{c}55=b\times 5\\ b=\frac{55}{5}\\ =11cm\end{array}$

Therefore, the base of the rectangle is11cm .
