Question

The base of a rectangle is 16cm and area is $80c{m}^2$ .What is the height?

Step-by-Step Solution

Answer

The height of the rectangle is  5cm

Step 1. Given information.

Base of the rectangle$b=16cm$

Area of the rectangle $A=80c{m}^2$.

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 base and area into the formula and find the height.

Area of the rectangle :

$\begin{array}{c}80=16\times h\\ h=\frac{80}{16}\\ =5cm\end{array}$

Therefore, the height of the rectangle is 5cm.
