Solution
The perimeter of a right triangle is and the ratio of its three sides is . What is the area
of the triangle?
120cm 1.2 : 2 : 1.6
The ratio of the sides can be rewritten as . Since the circumference is , the three sides are ,
, and , respectively. Note that this is a right triangle, since .
Therefore, the area of the right triangle is .
1.2 : 2 : 1.6 = 3 : 5 : 4 = 30 : 50 : 40 120cm 30cm
50cm 40cm + =302
402
502
S S = × 30 × 40 = 6001
