Question

Jeremy is building a large deck for a community center. The deck is shaped as a rectangle. The width of the deck is 29 feet. The perimeter of the deck is to be at least 134 feet.

A. Write an inequatlity that represents all possible values for the length of the deck.
B. Solve algebraically to find all possible values for the length of the deck.

Answer 1

L= P/2-w
L=134/2-29
L=67-29
L=38

Answer 2

W = 29 ft

P = 134 ft


P = 2 L + 2 W = 2 ( L + W )

P > 134 ft

2 ( L + 29 ) > 134

2 L + 58 > 134 Substract 58 to both sides

2 L + 58 - 58 > 134 - 58

2 L > 76 Divide both sides by 2

L > 38 ftBosnian Sunday, September 9, 2012 at 10:06amOne correction in second line .
