Represent the length and width by L and W. Then L = W + 4.
Using the perimeter formula: P = 2L + 2W = 68 ft = 2W) + 2(W+4).
Solve for W: 68 = 2W + 2W + 8, or 4W = 60. Thus, W = 15 and L = 19.
The dimensions of the rectangle are 15 by 19 feet.
Answer:
My thought is x = 24, according to the calculations
Step-by-step explanation:
Look for a way to eliminate the squared.
Write and solve an equation of ratios:
1 in 50 mi
--------- = ----------
x 350 mi
Then 50x=350, and x = 7 (inches)
