The perimeter is the sum of all the sides of the polygon.
A triangle is a polygon that has three sides.
From the definitions, we understand that we know the sum of the three sides is 36 cm. One side is 16 cm, and we need to find the other two. It is known that two unknown parties are equal.
We can make an equation, where X denotes the unknown side.
16 + X + X = 36.
16 + 2 X = 36.
2 x = 36 – 16.
2 X = 20.
X = 10.
Answer: the unknown sides of the triangle are 10 cm.
