Answer:
width = 2.4
Explanation:
so we know that the formula to get an area of a square/rectangle is A=lw, where A is the area, l is the length, and w is the width.
we already have the area and the length, so all we need now is the width.
to find the width, simply plug in the area and the length into the formula, which will give you:
A = lw -given formula
12 = 5(w) -plug in known variables
12/5 = 5w/5 -divide both sides by 5 to get x by itself
2.4 = w -turn the fraction into decimal if you prefer it that way
possible answers: w = 2.4, w = 12/5, or w = 2 2/5
