Question

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

Answer 1

110 feet

Explanation:

Given that,

Length of the rectangular garden = 9 1/4 feet = 37/4 feet

Width of the rectangular garden = 4 1/2 feet = 9/4 feet

We need to find the total length of fencing Mark needs to surround all 4 gardens.

The length for 1 garden = perimeter of the garden

The length for 4 garden = 4×perimeter of the garden

= 4×2(l+b)

`=8(l+b)\\\\=8((37)/(4)+(9)/(2))\\\\=8* 13.75\\\\=110\ \text{feet}`

Hence, 110 feet is the total length of the fencing Mark needs to surround all 4 gardens.
