Solution

The correct option is B $10 c m^{2}$
Given that base BC = 5 cm and the corresponding altitude, AP = 4 cm.

$∵$ Area of a triangle = $\frac{1}{2} \times (b a s e \times h e i g h t)$

$\Rightarrow$ Area = $\frac{1}{2} \times 5 \times 4$

= $10 c m^{2}$

Find the area of the triangle ABC.

The correct option is B 10 cm2Given that base BC = 5 cm and the corresponding altitude, AP = 4 cm. ∵ Area of a triangle = 12×(base×height) ⇒ Area = 12×5×4 = 10 cm2

The correct option is B $10 c m^{2}$
Given that base BC = 5 cm and the corresponding altitude, AP = 4 cm.

$∵$ Area of a triangle = $\frac{1}{2} \times (b a s e \times h e i g h t)$

$\Rightarrow$ Area = $\frac{1}{2} \times 5 \times 4$

= $10 c m^{2}$
