Question
Find the area in square centimeters of a triangle whose base and altitude are as under:
Base = 18cm, altitude = 3.5cm
Base = 18cm, altitude = 3.5cm
✓
Answer
We know that the area of a triangle $=\frac{1}{2}\text{(Base}\times\text{Height)}$
Here, base = 18cm and height = 3.5cm
Area of the triangle $=\frac{1}{2}\times18\times3.5$
$=31.5\text{cm}^2$
Here, base = 18cm and height = 3.5cm
Area of the triangle $=\frac{1}{2}\times18\times3.5$
$=31.5\text{cm}^2$
