Question

What is the area of a right angled triangle if its sides are 6cm, 8cm and 10cm?

• A. $26{cm}^2$
• B. $24{cm}^2$​
• C. $36{cm}^2$​
• D. $40{cm}^2$​

Answer 1

The correct option is B

$24{cm}^2$​

Area of triangle = $\frac{1}{2}\times base\times height$

The hypotenuse is the longest side of a right-angled triangle. Hence, the base and the height are 6 cm and 8 cm.
$\therefore \text{area}=\frac{1}{2}\times 6\times 8$
$=24c{m}^2$
