The width of a rectangle is fixed at 6cm. Determine(in terms of inequality) those lengths for which the area will be less than 150cm^2.
The length must be less than____cm.(simplify)
The solution is {L | L < ________cm}

Answer 1

A = W * L. W = 6cm, A<150cm^2

6cm * L < 150cm^2

L< 150/6 cm

Answer 2

6 L < 150

L < 25

Length must be less than 25 cm

{ L | L < 25 cm }

Answer 3

L<24cm

Answer 4

7,s=6x7<150

Answer 5

6L<150
L<150/6
L<25
{LIL<25cm}
