A seed company planted a floral mosaic of a national flag. The perimeter of the flag is 2,240 ft. Determine the flags width and length if the length is 420 ft greater than the width

the length of the flag is 770ft.

The width of the flag is 350 ft

Step-by-step explanation:

Let L represent the length of the national flag.

Let W represent the width of the national flag.

The formula for determining the perimeter of a rectangle is expressed as

Perimeter = 2(L + W)

The perimeter of the flag is 2,240ft. This means that 2240 = 2(L + W)

Dividing through by 2, it becomes

1120 = L + W- - - - - - - - - - - -1

if the length is 420 ft greater than the width, it means that

L = W + 420

Substituting L = W + 420 into equation 1, it becomes

1120 = W + 420 + W

2W + 420 = 1120

2W = 1120 - 420 = 700

W = 700 / 2 = 350

L = W + 420 = 350 + 420

L = 770
