Kerala Board Solutions for Chapter: New Numbers, Exercise 2: Exercise 2

The hypotenuse of a right triangle is $1\frac{1}{2}$ metres and another side is $\frac{1}{2}$ metre. Calculate its perimeter correct to a centimetre.

The picture shows an equilateral triangle cut into halves by a line through a vertex. What is the perimeter of a part?

The picture shows an equilateral triangle cut into halves by a line through a vertex. How much less than the perimeter of the whole triangle is this?

The perimeter of the triangle shown below is

We have seen how we can draw a series of right triangles as in the picture. What are the lengths of the sides of the tenth triangle drawn like this?

We have seen how we can draw a series of right triangles as in the picture. How much more is the perimeter of the tenth triangle than the perimeter of the ninth triangle?

We have seen how we can draw a series of right triangles as in the picture. How do we write in algebra, the difference in perimeter of the n^th triangle and that of the triangle just before it?

What is the hypotenuse of the right triangle with perpendicular sides $\sqrt{2}$ centimetres and $\sqrt{3}$ centimetres? How much larger than the hypotenuse is the sum of the perpendicular sides?
