Question

Find Area of $△ABC$ using formula $Area=\frac{1}{2}\times Base\times Attitude$

• A. $170c{m}^2$
• B. $180c{m}^2$
• C. $190c{m}^2$
• D. $200c{m}^2$

Answer 1

Answer: (B)

$180c{m}^2$

It is given that $△ABC$ has base $BC=40$ cm, height $AB=9$ cm and hypotenuse $AC=41$ cm.

General formula of area of triangle is:

$A=\frac{1}{2}\times base\times height=A=\frac{1}{2}\times 40\times 9=180$ cm${}^2$

Hence, area of triangle is $180$ cm${}^2$.
