a = Lw
Lw = 1/2
w = (1/2)/L
---
L = 3/8
---
w = (1/2)/L
w = (1/2)/(3/8)
w = (1/2)*(8/3)
w = (1/1)*(4/3)
---
answer:
w = 4/3 inch

Let's put this into the area formula. The formula for the area of a triangle is . A is area, l is length, and w is width. We already know the area, , and the length, , so let's plug that in.

Now divide from both sides. Divide by . When we divide fractions, you flip the fraction you are dividing by and multiply it to the original fraction. So we multiply by .

Simplify .

Now we know that , so the width is 4/3 inches. Hope I helped! :)
