The area of the rectangle whose length is 36m and width is 20m.
a) 112m2
b) 56m2
c) 720m2
d) 720m
Explanation: To find the area of a rectangle, we multiply its length by its width.
In this case, the length of the rectangle is 36m and the width is 20m.
Area = Length × Width Area
= 36m × 20m Area = 720m²
Therefore, the area of the rectangle is:
c) 720m²
The area of a parallelogram whose height is 2cm and base is 5.4cm
a) 2.4cm2
b) 10.8cm2
c) 4.2cm2
d) 3.6cm2
Explanation: To find the area of a parallelogram, we multiply its base length by its height.
In this case, the base of the parallelogram is 5.4cm and the height is 2cm.
Area = Base × Height Area
= 5.4cm × 2cm Area = 10.8cm²
Therefore, the area of the parallelogram is: b) 10.8cm²
A student obtained 40, 50 and 60 marks in
English, Maths and Urdu having weights 5,4 and 1 respectively. The mean is:
a) 44
b) 45
c) 46
d) 47
Explanation: Weights means
(40 × 5 ) + (50 × 4) + (60 × 1)
= 200 + 200 + 60 = 460 divided by(5+4+1) = 460/10 = 46
Divide 40 by half and add ten. The answer is.
a) 15
b) 14
c) 30
d) 11
Explanation: Half of 40 is 20, so 20+10 = 30
