(4.5 - 2.5)+(4.5 - 3.0)+(7.5 - 3.5)
=2+1.5+ 4
= 7.5 cm = 8 cm (approx.)

Olympiad Test: Understanding Elementary Shapes - Question 4

Which is the longest rectangle ?

Detailed Solution for Olympiad Test: Understanding Elementary Shapes - Question 4

By observing & comparing the given figures, rectangle B is the longest rectangle.

Olympiad Test: Understanding Elementary Shapes - Question 5

What is an angle which measures more than 0∘ and less than 90 called?

Olympiad Test: Understanding Elementary Shapes - Question 6

How is the measure of an angle expressed?

Olympiad Test: Understanding Elementary Shapes - Question 7

By what measure is the line m longer than the line n?

Detailed Solution for Olympiad Test: Understanding Elementary Shapes - Question 7

Length of line A = 9 cm

Length of line B = 7−2 = 5 cm

Length of line A − length of line B = 9 − 5 = 4 cm

Hence, line A is 4 cm longer than line B.

Olympiad Test: Understanding Elementary Shapes - Question 15

When an arm of an angle is extended then how does its measure change?

Olympiad Test: Understanding Elementary Shapes - Question 16

Which of the following angles is the measure of a reflex angle?

Detailed Solution for Olympiad Test: Understanding Elementary Shapes - Question 16

Reflex angles are those that "bend back" on themselves, creating an angle larger than a straight line (180°) but not completing a full circle (360°). Therefore, 270° fits the definition of a reflex angle.

So, the correct answer is 270°.
