Problem

Find the area of a triangle whose altitude and base are 15 cm and 10 cm, respectively.

2

Step

Here the given data is

Base = 15 cm, height = 10 cm

3

Formula

The area (A) of a triangle can be calculated using the formula: A = \$(1/2) \times (b) \times (h)\$

4

Step

Substitute the values into the formula:

A = \$(1/2) \times (15) \times (10)\$

5

Step

Solving this expression :

A = \$(150)/2\$

A = \$75 cm^2\$

6

Solution

So, the area of a triangle is 75 sq cm.
