You'll have to work out the length of the third side using:
a) the sine rule (if information given has one side opposite a given angle and the unknown side also opposite a given angle)
SIN RULE: sinA/a = sinB/b = sinC/c
b) the cos rule (not opposite).
COSINE RULE: a2 = b2 +c2 -2bc x CosA

What is the perimeter of a triangle whose sides measure 10 cm 15 cm and 18 cm?
Perimeter of a triangle is given by: sum of the three sides =(10+15+18)cm =43cm Done.
What is the perimeter of an equilateral triangle whose sides measures 8.5 meters?

How to find the perimeter of an eQuilateral triangle whose sides measure 5 cm?
The figure is a triangle. That means it has 3 sides. The triangle is "equilateral". That means all three sides have the same length. One side is 5 cm. That means each of the other 2 sides is also 5 cm. So the perimeter is (5 + 5 + 5) = 15 cm.
What is the irregular shape with the perimeter of 36cm?
It could be any irregular shape whose sides add up to 36cm as for example a scalene triangle

What is the perimeter of a triangle whose sides measure 6 8 and 10 inches?
6+8+10=24The perimeter of the triangle is 24 inchesThe perimeter is all the side lengths added up, so that triangle would have a perimeter of 24 inches.6+8+10=24 inches
What is the perimeter of a triangle whose sides measure 15 cm 17 cm and 10 cm?
To find the perimeter of a triangle, you simply add the lengths of all three sides together. In this case, the perimeter would be 15 cm + 17 cm + 10 cm = 42 cm. So, the perimeter of the triangle with sides measuring 15 cm, 17 cm, and 10 cm is 42 cm.
