, Question 1
What shape’s area is calculated using AA=2aa+bh?
This formula is for the area of a trapezium.
A. Area of a trapezium
B. Volume of trapezium
C. Area of a triangle
D. Area of a circle
Answer: A. Area of a trapezium


Question 2
What is the volume of this liquid?
Image shows a measuring cylinder with liquid meniscus just above 70 mark, and 3 small
divisions above 70.
There are 5 divisions between 70 and 80. So each small division represents
(80−70)/5=10/5=2 units.
The liquid level is at the third division above 70.
So, the volume is
70+(3×2)=70+6=76 units.
Looking at the options, none are exactly 76. Let's re-examine the image.
The bottom of the meniscus is slightly below the 3rd mark. It's exactly halfway between the
second and third mark, or perhaps exactly on the second mark. If it's exactly on the second mark,
it's 70+(2×2)=74. If it's halfway between the second and third mark, it's 70+(2.5×2)=70+5=75.
Option C is 75 ml. Option D is 75 cm. Volume is typically measured in ml for liquids in
measuring cylinders.
Answer: C. 75 ml


Question 3
Which metric unit(s) of measurement measure volume?
A. ml
B.
