medium MCQ 2 marks Class 5 · Mathematics · Area and its Boundary

Answer

60 cm ^2

The correct answer is 60 cm ^2 — The area is $60 cm^{2}$ .

Step-by-step solution

Use the formula for the area of a right triangle: $A = \frac{1}{2} \times a \times b$ , where $a$ and $b$ are the two legs.
Substitute $a = 8$ and $b = 15$ : $A = \frac{1}{2} \times 8 \times 15$
$8 \times 15 = 120$
Divide by 2: $120 d i v 2 = 60$
The area is $60 cm^{2}$ .

Common mistake: Forgetting to multiply by

\frac{1}{2}
