Question

Area of the given quadrilateral can be written as Ar(ΔABC) + Ar(ΔACD).

• A. True
• B. False

Answer 1

The correct option is A

True

When we connect the vertices A and C with line segment AC, then the given quadrilaterals is divided into two triangles $\Delta$ABC and $\Delta$ADC

A quadrilateral area can be expressed as a sum of the area of the two triangles formed by drawing one of its diagonals. ​​​​​​​
So, area of quadrilateral = Ar(ΔABC) + Ar(ΔACD)
