Answer 1

Rectangle E has a side length of 5 and an area of 20. We can find the other side easily; since area = length * width, 20 = 5 * width; width = 20/5 = 4.
So, rectangle E is 5 by 4.
We need to find the area of rectangle F. We know the length is 3.75, and we can find the width based on the ratio with the
Rectangle F has a ratio of 3.75/5 compared to the rectangle E. So, the width of F should be (3.75/5) multiplied by the width of E, which we found to be 4.

First, what is the width of rectangle F? From there, we can multiply length by width to find the area

Answer 2

its 3.75 the width

Answer 3

Gotcha, I was using length and width interchangeably, that's fine.
So, if we say the "width" is 3.75, what would be the "length"? We can use the ratio (3.75/5) to find calculate this. The length of rectangle F should be 4 * (3.75/5)

Answer 4

3

Answer 5

That's right. Then, the area of rectangle F would be its width multiplied by its length. So, what does that give us?

Answer 6

so 3*3.75?

Answer 7

Yes, that's right

Answer 8

11.25

Answer 9

Yes, that's right.
Incidentally, we could have also gotten the answer by multiplying the area of rectangle E by the ratio (3.75/5)^2. (For the sake of simplicity, 3.75/5 equals 0.75 or 3/4)
In other words, 20 * 0.75 * 0.75 would also give us the answer, 11.25
In any case, you got it!
