How long is a rectangle field with a width of 3/5 mile and an area if 21/50 square mile? Use the formula A=lw to find the missing length.

____21/50 = l x 3/5

_____0.42 = l x 0.6

0.42/0.42 = l x 0.6/0.42

l = 0.7

0.42 = 0.7 x 0.6

21/50 = 7/10 x 3/5

So, l's length is 7/10.

I hope this helps! :)

Thank u so much

You're welcome Amy! :)

To find the missing length of the rectangle field, we can use the formula A = lw, where A represents the area, l represents the length, and w represents the width.

Given that the width of the rectangle field is 3/5 mile and the area is 21/50 square mile, we can substitute these values into the formula:

A = lw
21/50 = l * 3/5

To find the missing length, we need to isolate l.

First, we can simplify the equation by multiplying both sides by 50 to eliminate the fraction:

(21/50) * 50 = l * (3/5) * 50
21 = 30l

Next, we can solve for l by dividing both sides of the equation by 30:

21/30 = l * (30/30)
7/10 = l

Therefore, the missing length of the rectangle field is 7/10 mile.
