Question

If (s -a) = 5cm, (s -b) = 10cm, (s -c) = 1cm then find s

Answer 1

• s = 1/3 (a + b + c + 16)

Step-by-step explanation:

Given

• If (s -a) = 5cm, (s -b) = 10cm, (s -c) = 1cm
• s = ?

Solution

Add up the 3 equations and solve for s:

• s - a + s - b + s - c = 5 + 10 + 1
• 3s = 16 + a + b + c
• s = 1/3 (a + b + c + 16)
