Question on: WAEC Mathematics - 2001
In the diagram, MN||PQ, |LM| = 3cm and |LP| = 4cm. If the area of ∆LMN is 18cm2, find the area of the quadrilateral MPQN
A
3cm2
B
6cm2
C
14cm2
D
24cm2
Ask EduPadi AI for a detailed answer
Correct Option: B
Using similar triangles
(\frac{3}{16}=\frac{4}{x}<br />
x = \frac{18\times4}{3}=24cm^2)
∴Area of quadrilateral MPQN
(=24cm^2 - 18cm^2 = 6cm^2)
