Question

Two sides of a quadrilateral are 64cm and 48cm in length and the angle between them is 90°. The other two sides are 50cm each. The other three angles of the quadrilateral are not right angles. What is the area of the quadrilateral ? ​

Answer 1

Explanation:-

<ABC is 90°

so it is a right angle.

So the area of ABC =48×64/2 cm²

ADC is a triangle in which AC = 80 cm

s = (50+50+80)/2

s = 90cm

Area of ADC =900 cm²

Total area = area of ABC+ ADC

=900+90cm²

=990cm²
