Question

Todd and his friends are painting 5 equal sections of a wall. The wall is 10 feet tall, but its length is unknown. Each section will be a different color, so they need to know the area of each section.
1. Write an expression for the total area of the wall. Explain how you came up with your expression.

2. To find the area of each section, what do you need to do to the total area?

3. Write an expression for the area of each section of the wall.

I don't understand how to find the total areas and what equations to write.

Answer 1

The expression for the total area of the wall is 10x.

The area of each section is 2x.

How to find the area of a rectangle?

The wall is 10 feet tall, but its length is unknown.

The whole wall is rectangular.

Therefore,'

area of a rectangle = lw

where

• l = length
• w = width

Therefore, the expression for the total area of the wall is as follows;

area = 10x

The area of each section can be found by dividing the length of the whole wall by 5 and multiplying by 10.

Therefore,

area of each section = x / 5 × 10

area of each section = 10 / 5 x

area of each section = 2x
