Question

Find the area of a right-angled triangle whose base is 8 cm and height is 9 cm.

• A. $48c{m}^2$
• B. $20c{m}^2$
• C. $60c{m}^2$
• D. $36c{m}^2$

Answer 1

The correct option is D

$36c{m}^2$

Area of right triangle $=\frac{1}{2}\times base\times height$
$=\frac{1}{2}\times 8cm\times 9cm$
$=36c{m}^2$
