Answer:
Step-by-step explanation:
perimeter of rectangle = 1100
let breadth be x
length = 300 + x
perimeter of rectangle = 2(l + b)
1100 = 2(300 + x + x)
1100 = 2(300 + 2x)
1100 = 600 + 4x
1100 - 600 = 4x
500 = 4x
500/4 = x
125 = x
therefore breadth is 125 feet
length = 300 + 125
=425 feet
Answer:
The rectangular field is 425 feet by 125 feet.
Step-by-step explanation:
Let w represent the width of the rectangular field.
Since the length is 300 feet more than the width, the length can be modeled by the expression (w + 300).
The perimeter of a rectangle is given by the formula:
[tex]P=2(w+\ell)[/tex]
Where P is the perimeter and w and l are the width and length, respectively.
We are given that the perimeter is 1,100 feet. Substitute:
[tex]1100=2(w+\ell)[/tex]
Divide both sides by two:
[tex]550=w+\ell[/tex]
We know that l = (w + 300). So:
[tex]550=w+(w+300)[/tex]
Simplify:
[tex]2w=250[/tex]
Divide both sides by two. So, the width is:
[tex]w=125\text{ feet}[/tex]
Since the length is 300 feet more than the width, that means the length is 425 feet.
The rectangular field is 425 feet by 125 feet.
