Area of triangle whose base is 9cm and height 10cm

The formula for the area of a triangle is:

\[
\text{Area} = \frac{1}{2} \times \text{Base} \times \text{Height}
\]

Here, the base is 9 cm and the height is 10 cm. Substituting these values:

\[
\text{Area} = \frac{1}{2} \times 9 \times 10 = \frac{1}{2} \times 90 = 45 \, \text{cm}^2
\]

Thus, the area of the triangle is **45 cm²**.
