Question

Which all formula we can use to find the area of triangle

• A. True
• B. False
• C. $\frac{1}{2}\times BD\times AD$
• D. $\frac{1}{2}\times BC\times AD$

Answer 1

Answer: (A), (D)

The correct options are
A

True

D

$\frac{1}{2}\times BC\times AD$

Area of the triangle can hence be given in two forms. The area of triangle could be given by heron’s formula by first calculating the semi perimeter (s) of the triangle and using the formula $\sqrt[2]{2s(s-a)(s-b)(s-c)}$ OR by dropping a perpendicular and then finding out the area using the formula 1/2 $\times$ base $\times$ height.
