In a triangle, the base is $14\text{ cm}$ and the height is $9\text{ cm}$. What is its area?

Step-by-step solution

1. Step 1: Use the formula for the area of a triangle $A=\frac{1}{2}\times \text{base}\times \text{height}$, because a triangle’s area is one‑half of base times height.
2. Step 2: Substitute the given values: $A=\frac{1}{2}\times 14\times 9$.
3. Step 3: Multiply $14\times 9=126$.
4. Step 4: Divide by 2: $A=126/2=63$.
5. Step 5: The area is $63{\text{ cm}}^2$.
