Question

1 unit
area = square units

Explanation:

Step1: Identify base and height

The base of the right - angled triangle is 4 units and the height is 3 units.

Step2: Apply triangle area formula

The area formula for a triangle is $A=\frac{1}{2}\times b\times h$, where $b$ is the base and $h$ is the height. Substitute $b = 4$ and $h=3$ into the formula: $A=\frac{1}{2}\times4\times3$.

Step3: Calculate the area

$\frac{1}{2}\times4\times3 = 6$.

Answer:

6
