Question

What is the perimeter of a rectangle that has the base of 10 and a height of 5

Answer 1

Perimeter = is the sum of the lengths of a geometrical figure.

In this case we have a rectangle, so in order to calculate the perimeter we must sum the 4 sides of the rectangle.

The sides are:

b = 10

h = 5

So the perimeter is:

`P=b+b+h+h=10+10+5+5=30`

We sum twice the base and the height because they appear twice in the rectangle!
