Question

In ∆ ABC AB=6, BC=8AC=10. ∆ ABC is enlarged to ∆ PQR such that the largest side is 12.5cm.What is the length of the smallest side of ∆ PQR

Answer 1

Answer:

8.5cm

Step-by-step explanation:

In triangle ABC,

AB = 6

BC = 8

AC = 10

So the largest side here is AC = 10cm

In triangle PQR,

Largest side = 12.5 = 10 + 2.5 = AC + 2.5

So the other two sides are,

BC + 2.5 = 8 + 2.5 = 10.5

AB + 2.5 = 6 + 2.5 = 8.5

Therefore the smallest side is 8.5cm
