Question 1063278: A seed company planted a floral mosaic of a national flag. The perimeter of the flag is 460 feet. Determine the flag's length and width if the length is 70 feet greater than the width.
Answer by Boreal(15235)   (Show Source):
You can put this solution on YOUR website! Perimeter is 2L+2W
Therefore, half the perimeter is L+W
Half of 460 is 230
L+W=230, since they are half the perimeter
W+70+W=230, since L=70 more than W, or W+70
2W+70=230
2W=160, subtracting 70 from both sides
W=80 feet, dividing both sides of the equation by 2.
L=150 feet
2W=160 feet
2L=300 feet
Total is 460 feet check.
