Question

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

Short answer

The height of the rectangle is 5cm

Step-by-step solution

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.
