Answer:
Explanation:
To find out how much of the 100 foot roll of fencing Martin will need to enclose the garden, you need to calculate the perimeter of the rectangular garden.
The perimeter is the total distance around the garden. To find the perimeter, you add up the lengths of all four sides of the rectangle.
The formula for the perimeter of a rectangle is: P = 2L + 2W
Where P is the perimeter, L is the length, and W is the width.
In this case:
P = 2 x 10 feet + 2 x 100 feet = 20 feet + 200 feet = 220 feet
Martin will need 220 feet of fencing to enclose his rectangular garden.
