John is a garden with dimension 7 feet long X6 feet wide. He wants to enlarge the garden to an area of 108 ft.². How much farther will you need to extend the length of garden to attain his desired area
The current area of the garden is 7 feet x 6 feet = 42 ft².
To attain the desired area of 108 ft², the new dimensions of the garden can be calculated using the formula:
new length x new width = desired area
let new length = x
x x 6 = 108
x = 108 / 6
x = 18
So, the new length of the garden should be 18 feet.
To calculate how much farther John needs to extend the length, we subtract the current length from the new length:
18 ft - 7 ft = 11 ft
John will need to extend the garden by an additional 11 feet to attain his desired area of 108 ft².
