Word Problem

Question

Terri wants to put a fence around her tomato plants to keep the rabbits ut. The hardware store only sells fencing in five foot increments. How much wire does she need to buy in order to go around all of the plants, if the area they cover is 150ft^2?

Answer 1

The question is not truly answerable as phrased because there

are various lengths and widths (assuming the plants are in a

rectangular plot) that would create an area of 150 ft²

 

The area = length*width

Perimeter = 2(length + width)

 

Possibilities (with whole number length and width)

 

3 ft by 50 ft = 150 ft² area

(3+50)2 = 106 ft of fencing

106/5 = 21 rolls + 1 more to cover the extra ft

22 rolls = 110 ft

 

 

15 ft by 10 ft = 150 ft² area

2(15+10) = 50 ft of fencing

10 rolls

 

75 ft by 2 ft = 150 ft² area

2(75+2) = 154 ft of fencing

31 rolls

 

25 ft by 6 ft = 150 ft² area

2(25+6) = 62 ft of fencing

13 rolls

 

You need to post the actual dimensions of the tomato plot
