Answer:
30m²
Step-by-step explanation:
To find the area of a triangle, you need to ensure that the triangle is a right-angled triangle. We can use the Pythagoras Theorem to help us prove that.
a² + b² = c²
5² + 12² = 169
13² = 169
By converse of Pythagoras Theorem, the triangle is a right-angled triangle.
Thus, you can directly find the area of the triangle using the formula: base × height ÷ 2.
Area = 12 × 5 ÷ 2
= 30m²
