Okay, so to solve these type of questions we need to use the pythagoras property, which is ⇨ Hypotenuse² = Base² + Altitude².

Here,

1. Hypotenuse (the longest side) = 5
2. Altitude (height) = 4
3. Base (the bottom line) = a

So, we have to find the base of the triangle .

Hypotenuse² = Base² + Altitude²

(5)² = (a)² + (4)²

25 = a² + 16

25 - 16 = a²

9 = a²

√9 = a

3 = a

• The length of side a is A. 3

• We used the pythagoras property to solve this question because the given triangle is a right angled triangle.
• Note that the pythagoras property only works in the case of right angled triangles.
