On a photograph of a triangular piece of  land, the lengths of the three sides are

4 cm, 6 cm, and 9 cm, respectively. The shortest side of the actual piece of land is 240m long.

Find the lengths of the other two sides.

The length of the longest side of the triangular piece of land is   _____

The length of the middle-sized side of the triangular piece of land is _____

240 / 4  =  60

So.....each side of the triangle on land will be  60  times the length of the side in the photo.

the longest side  =  9 * 60  =  540 m

the middle side  =  6 * 50  =  360 m

(Also.....do notice that the units are different, but it'll work out like this.)
