Question

The width of a rectangle is

fixed at 4 cm.
For what lengths, I will the
area be less than 86 cm??
Give your answer as an inequality,
using l as the variable for length

Answer 1

Explanation:

Area = L * W

L * W < 86

W = 4

L * W < 86

4L < 86

L < 86 / 4

L < 21 1/2

I think you should give this in terms of 4.

4 < L < 21 1/2

L should be larger than 4
