Calculate the ratio of two areas measuring 25 square metres and 5 square metres.

To find the ratio of two areas, you divide the larger area by the smaller area. In this case, you have two areas: 25 square metres and 5 square metres.

When you calculate the ratio, you take the area of 25 square metres and divide it by the area of 5 square metres:

[ \text{Ratio} = \frac{25 \text{ square metres}}{5 \text{ square metres}} = 5 ]

This calculation indicates that for every 1 unit of area represented by the smaller area of 5 square metres, there are 5 units represented by the larger area of 25 square metres. Therefore, the ratio of the two areas is 5 to 1.

This means that the larger area is five times greater than the smaller area, justifying why this answer is correct.
