Step by Step Solution

Step 1. Given information.

Length of the wooden fence=6ft

Height of the wooden ffence =220ft

Step 2. Concept  Used.

If bis the length of the wooden fence and h is the height of the fence.

Then, the area of the fence is A=b×h

Step 3. Let’s calculate the area of the fence.

Put the value of length and height into the formula and find the area.

Area of the fence :A=220×6=1320ft2

Since, it is to be painted on both sides the painted area gets doubled



So, area to be painted is 2640ft2

In the first coat 200ft2=1




In the second coat300ft2=1





Total paint gallon

Therefore, the area to be painted is2640ft2 and total paint required is 22gallon.
