Area of a right triangle is 1/2 x height x base

The area of the first triangle is 1/2 x 12 x 15 = 90 square cm.

The area of the other triangle is 90 and one side is 18:

90 = 1/2 x 18 x S

Multiply both sides by 2:

180 = 18 x S

Divide both sides by 18:

S = 180/18

S = 10

The length of the other side is 10 centimeters
