In the diagram, PQST and QRST are parallelograms. Calculate the area of the trapezium PRST.
Attached Figure / Diagram
A
60cm2
B
50cm2
C
40cm2
D
30cm2
Verified Correct Answer: D.
Step-by-Step Mathematical Solution
PR = 4 + 4 = 8 cm
Area of trapezium = \(\frac{1}{2} (a + b) h\)
= \(\frac{1}{2} (4 + 8) \times 5\)
= 30 cm\(^2\)
