The gardener needs to make a rectangular garden plot which has an area less than 16ft².The width should be 6 feet shorter than the length. What are/is the possible dimensions?

Answer 1

Possible combinations

L W

7.21 2.21

7 2

6 1

5.1 0.1

7.22 > L > 5

2.22 > W > 0

W = L-5

A < 16 = LW = L(L-5) = L^2 -5L

L^2 -5L- 16 < 0

L < 5/2 + (1/2)sqr(25+64) = + sqr89/2 = about 7.217 long or less

W < about 2.217 feet wide
