Respuesta :
l = 2w + 5
2l + 2w = 61
2(2w + 5) + 2w = 61
4w + 10 + 2w = 61
6w = 51
w = 51/6
w = 8.5
l = 22
The length of the garden is 22 feet and the width of the garden is 8.5 feet and this can be determined by forming the linear equation.
Given :
- The perimeter of Dana's rectangular garden is 61 feet.
- The length of her garden is 5 feet more than twice the width.
The following steps can be used in order to determine the length and width of the garden:
Step 1 - Let 'L' be the length of the garden and 'w' is the width of the garden.
Step 2 - The linear equation that represents the length of Dana's garden is 5 feet more than twice the width is given by:
L = 5 + 2w --- (1)
Step 3 - The linear equation that represents the perimeter of Dana's rectangular garden is 61 feet is given by:
2L + 2w = 61 --- (2)
Step 4 - Substitute the value of L in equation (2).
2(5 + 2w) + 2w = 61
Simplify the above equation.
10 + 4w + 2w = 61
6w = 51
w = 8.5 feet
Step 5 - Substitute the value of 'w' in equation (1).
L = 2(8.5) + 5
L = 17 + 5
L = 22 feet
So, the length of the garden is 22 feet and the width of the garden is 8.5 feet.
