Answer:

Step-by-step explanation:
Let w and l be the width and length of the garage.
Let
and
be the area of garage at present and new garage.
Given:
The area of the garage at present

And he planed to tripling the dimensions of the garage.
We need to find the area of the new garage.
Solution:
We know the area of the rectangular garage.


---------------(1)
The dimension of the new garage is triple, so the area of the new garage is.


Substitute
from equation 1.


Therefore, the area of the new garage 
Difference of squares makes (x+3)(x-3)/(x+3)
The x+3’s cancel out
Answer is x-3
For this problem, the total length of fencing is equivalent to the perimeter of a rectangle. The formula for the perimeter of a rectangle is written below:
P = 2L + 2W
where L and W are the length and width dimensions
From the relationship described,
P = 350,350 ft
W = 2/3 L
Substituting this to the perimeter equation:
350,350 = 2L + 2(2/3 L)
Solving for L,
L = 105,105 ft
W = (2/3)(L) = (2/3)(105,105) = 70,070 ft
