39cm ≤ P ≤41cm
38cm ≤ P < 42cm
38.5 ≤ P ≤ 41.5cm
38.5 ≤ P ≤ 40cm
Correct answer is B
If the side = 10 cm, correct to the nearest whole number, then
The side ranges from 9.5 cm to 10.5 cm. (9.5 \(\leq\) s < 10.5)
Perimeter of a rhombus = 4 x side
\(\therefore\) 4 x 9.5 \(\leq\) perimeter < 4 x 10.5
= 38 cm \(\leq\) P < 42 cm
Arrange in ascending order of magnitude \(26_8, 36_7, and 25_9\)
\(25_9 26_8 36_7\)
\(26_8 25_9 36_7\)
\(36_7 26_8 25_9\)
\(36_7 25_9 26_8\)
Correct answer is B

The side of a square is increased from 20cm to 21cm. Calculate the percentage increase in its area
2.5%
9.3%
10.0%
10.25%
Correct answer is D
old area = 202 = 400
new area = 212 = 441
% increase in area \(=\frac{41}{400}\times \frac{100}{1}\\
=10.25\%\)
