Question

Form algebraic equations
The perimeter of a triangle with two
equal sides of length 13 cm each is 42
cm. Find the length of the other side.​

Answer 1

Answer:

16 cm

Step-by-step explanation:

Δ ABC

P = AB + BC + AC

Assume AB = BC = 13, then AC = x

2 × 13 + x = 42 ⇔ 26 + x = 42

x = 42 - 26

x = 16 cm
