ABCD is a rectangle with a length of 10 cm and a breadth of 3 cm. If AC is diagonal, then what is the area of triangle ABC?

Given,

The length of a rectangle = 10 cm

The breadth of a rectangle = 3 cm

Area of triangle ABC = $\frac{1}{2}$ (Area of rectangle ABCD)

= $\frac{1}{2} (length \times breadth)$

= $\frac{1}{2} (10 \times 3)$

= $\frac{1}{2} \times 30$

= 15 cm²

Therefore, the area of triangle ABC is 15 cm².
