Question

The lengths of the sides of a triangle are 5 cm, 12 cm and 13 cm. What is the length of altitude from the vertex opposite to the side of length 5 cm?

Answer 1

Explanation:

• First construct a triangle of given lengths.
• Using herons formula, find the area of triangle.
• $herons \: formula \\ \sqrt{s(s - a)(s - b)(s - c)}$
• ' S ' represents semi perimeter.
• S= a+b+c/2
• Take a=12, b=13, c=5.
• Now, equate the area of triangle with the general area formula.
• $area \: of \: triangle \\ = \frac{1}{2 } \times base(b) \times height(h ) \\ = \frac{1}{2} \times b \times h$
• While equating take the base(b) as the length of 5cm .
• By,calculating you can get the length of the altitude required.
