The area of the square is 40,000 square feet so the square's side length is 20 (√40,000).

The company charges $2.50 per foot, and the perimeter is 80 (20*4), so the  cost is $400 ($2.50 * 8).

Add on the $50 installation fee and the total cost is $450 ($400 + $50).

Is 3/4 bigger than 3/5
Svet_ta [14]
Yes, 3/4 is bigger than 3/5.
One way you can verify this is by drawing a bar model, and cut it into four. Color in three pieces.
Then, draw another bar model the same size as the first one, and cut it into five pieces.
Color in three pieces.
You can see that 3/4 has more shaded in area than 3/5.
Another way you can do this is by dividing the numerator by the denominator for both fractions.
Hope this helped.
