Question

A seed company planted a floral mosaic of a national flag. The perimeter of the flag is 500 feet. Determine the flag’s length and width of the length is 70 feet greater than the width.

Answer 1

The width is w
The length is w + 70
Perimeter: p = 2(l + w) and =500
Substitute what you know:
500 = 2(w+ 70 + w)
Combine like terms:
500 = 2( 2w + 70)
Distribute 2 to both terms
500=4w-140
640 = 4w
w = 640/4 = 160 feet L= w +70= 160 + 70= 230 ft.
