Answer:

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

Step-by-step explanation:

<u><em>The correct question is</em></u>

The perimeter of the flag is 2080 ft what is the flags width and length <u>if</u> 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

P=2(L+W)

we have

P=2,080\ ft

so

2,080=2(L+W)

1,040=L+W ----> equation A

L=W+420 ---> equation B

Solve the system by substitution

substitute equation B in equation A

1,040=(W+420)+W

solve for W

1,040=2W+420

2W=1,040-420

2W=620

W=310\ ft

<em>Find the value of L</em>

L=W+420 ----> L=310+420=730\ ft

therefore

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