Lisa is painting a fence that is 26 feet long and 7 feet tall. A gallong of paint will cover 350 square feet. Write and solve a proportion to determine how many gallons of paint Lisa will need.
Thanks, Ms. Sue for the last one...I got it!
area=l*w
26*7/350=Volume/1gallon
volume= 26*7/350 gallons
To determine how many gallons of paint Lisa will need, we can set up a proportion based on the area she needs to cover. The area of a rectangle can be found by multiplying its length by its height.
In this case, the length of the fence is 26 feet and the height is 7 feet. So, the area of the fence can be calculated as 26 feet * 7 feet = 182 square feet.
Now, we can set up a proportion based on the given information that 1 gallon of paint will cover 350 square feet. Let's use "x" to represent the number of gallons of paint Lisa will need. The proportion can be set up as:
x gallons / 1 = 182 square feet / 350 square feet
To solve this proportion, we can cross-multiply:
x * 350 = 1 * 182
x * 350 = 182
Now, divide both sides of the equation by 350:
x = 182 / 350
x ≈ 0.52
Therefore, Lisa will need approximately 0.52 gallons of paint to cover the fence.
