Mark wants to fence 4 rectangular gardens, each with a length of 9 1/4 feet and a width of 4 1/2feet. What is the length of fencing mark needs to surround all 4 gardens

110 ft

Step-by-step explanation:

The length of fencing is four times the perimeter of one garden.

The formula for the perimeter of a rectangle is

P = 2l + 2w

The total perimeter for all four rectangles is

P = 4 * (2l + 2w) = 8l + 8w

dа ta:

l = 9¼ ft

w = 4½ ft

Calculation:

P = 8l + 8w = 8*9¼ + 8*4½ = 72⁸/₄ + 32⁸/₂ = (72 + 2) + (32 + 4) = 74 + 36 = 110 ft

The total length of fencing is 110 ft.
