Question

The area of triangle formed by the points (0, 0), (5, 0) and (0, 5) is

A) 5 sq. units 

B) 7.5 sq. units 

C) 10 sq. units 

D) 12.5 sq. units

Answer 1

Correct option is (D) 12.5 sq. units

Area of triangle \(=\frac12\times OA\times OB\)

\(=\frac12\times(5-0)\times(5-0)\)

\(=\frac{25}2\) = 12.5 square units

Answer 2

D) 12.5 sq. units
