Since the shortest side of the first triangle is 2, we know that 2 x 3 is 6, so the other sides are 3 times the sides of the first triangle. The other two sides are 9 and 12 (3 x 3 = 9 and 4 x 3 = 12). We can also solve these types of problems using proportions. Example 2: A rectangle has width equal to 10 feet and length equal …
