Let the length be (2x+75) and the width be x:
length*width = area in square yards
(2x+75)*x = 4050
2x2+75x-4050 = 0
Solving the above quadratic equation works out as:
x = -67.5 or x = 30 it must be the latter because dimensions can't be negative.
Therefore: length = 135 yards and width = 30 yards
Check: 135*30 = 4050 square yards

A rectangular field is to be enclosed with 1180 ft of fencing If the length of the field is 50 ft longer than the width then how wide is the field?
Length = x+50. Width = x 2(x+50+x) = 1180 2x+100+2x = 1180 4x = 1180-100 4x = 1080 x = 270 Width = 270 feet
What is the approximate length of a side of a square field that has an area of 479 ft?
Assuming you meant an area of 479 SQUARE feet, each side would be 21.9 feet
The length of a new rectangle playing field is 8 yards longer than quadruple the width If the perimeter of the rectangle playing field is 496 yards What are its dimensions?
The length is 200 yards and the width is 48 yards.length + width = 248 yards, and length = (4 x width) + 8 yards.substituting (4 x width) + 8 yards for length,(4 x width) + 8 yards + width = 248 yards;simplifying, width = 240/5 yards = 48 yards;then length = 248 - 48 yards = 200 yards

A square is removed from a rectangular field The perimeter of the field is 160 meters What is the length and width of original field?
The answer may vary. If you take a square away from the field it will still have the same perimeter. So the Length and Width may vary on how you make the field.
How many square feet on a 300' softball field?
If it's a rectangular field, you need to multiply the length by the width (both in feet), to get the area (in square feet).
Find the length of a square playground whose area is equal to the area of rectangular field of dimensions 72m and 388m?
First of all you need to calculate the area of the rectangular field. You do this by multiplying the length by the width. 72m x 388m = 27,936m2 If a square (which has four equal sides of course) has the same area then we can calculate the length of a side by finding the square root of the above. 27,936m1/2 = 167.14m (to 2 decimal places).

A cow is tied with a rope of length 10m at one of the corners of a rectangular field 40m.30m . The area of land grazed by the cow is?
The dimensions of the field are not used in solving this problem except to assure that they are longer than the length of rope. The question is solved by realizing that the cow will have access to a quarter circle and solving for this area. In this case, the answer is 78.54 square meters.
If the area of a square field is 2500m square how do you know the dimensions of the field are 50m by 50m?
The field is square, so you know that its length is the same as its width and so, its area is its length times its length. So find the square root of 2500 square metres and that is the length of each side of the square field.
What if the area of a rectangular field is 5073m2. if the length of the field is 89 m what is its width?
It is 57 metres.
The area of a rectangular field is 165m2 Its length is 15m what is the width of the field?
Area = Length * Width So Width = Area / Length = 165/15 = 11 metres.
