Answer:
20 cm
Step-by-step explanation:
perimeter= 70cm
two sides are 22 cm and 28 cm
therefore, third side = 70 - (22+28)
= 70 - 50
= 20 cm.

Answer:
20 cm
Step-by-step explanation:
perimeter = sum of all three sides of a triangle
so,
sum of sides = 22+28+ a
perimeter= 70
70 = 22+ 28 + a
70 = 50 + a
a = 70 - 50
a = 20 cm
