Question

Given that

a
= 5 cm and
b
= 14 cm, work out the area of the triangle.
Give your answer rounded to 1 DP

Answer 1

32.7

Explanation:

Using the Pythagorean theorem, we can set an equation to 5^2+c^2=14^2,

which is equal to 196-25 = c^2, which is equal to c^2=171, therefore, c=
`√(171)`

5*
`√(171)`/2=32.69, rounded will equal to 32.7
