Question

Please say me the answer. Plot a point A(0,3)and (6,0) in the Cartesian plane. Is Oab a triangle? If yes find area of the triangle AOB

Answer 1

yes .

OAB is a triangle.

Area of OAB =
= 1/2 × base × height
$= \frac{1}{2 } \times 3 \times 6 \\ = 9 \: square \: units$

Answer 2

➡HERE IS YOUR ANSWER⬇

Given ΔAOB a triangle. (See the attachment.)

Height = OA = 3 units

Base = OB = 6 units

We see that ΔAOB is a right-angled triangle.

Area of a right-angled triangle ΔAOB

= (1/2)×(Base×Height)

= (1/2)×(6×3) unit²

= 9 unit²
