The perimeter of the flag is 2080 ft what is the flags width and length of the length is 420 ft greater than the width

The length of the flag is 730 ft and the width is 310 ft

Step-by-step explanation:

The correct question is

The perimeter of the flag is 2080 ft what is the flags width and length if the length is 420 ft greater than the width

Let

L ----> the length of the flag

W ---> the width of the flag

we know that

The perimeter of the flag (rectangle) is equal to

we have

so

----> equation A

---> equation B

Solve the system by substitution

substitute equation B in equation A

solve for W

Find the value of L

---->

therefore

The length of the flag is 730 ft and the width is 310 ft

4th option is correct xy=-10
