Rajasthan Board RBSE Class 8 Maths Chapter 12 Linear Graph Ex 12.2

Question 1.
Length of a side of an equilateral triangle and square is x cm.
Find their perimeter, draw the(RBSESolutions.com)graph between length and perimeter.
[Hint = Perimeter of ∆ = (x + x + x) cm.]
Solution
(1) Perimeter of equilateral triangle = 3 x Length of one side
= 3x
Table for x and corresponding P

 Length(x) 1 2 3 4 5 6 Perimeter(P) 3 6 9 12 15 18

This shows a straight line.

(2) Perimeter (P) of square
= 4 x Length of one side
= 4x
Table for x and corresponding P

 Length(x) 1 2 3 4 5 6 Perimeter(P) 4 8 12 16 20 24

This shows a straight line.

Question 2.
Length of a rectangle is double of its breadth. Draw the graph between area and breadth of rectangle. (Hint : Area of rectangle A = 2x × x = 2x²) Solution
Breadth of rectangle (B) = x
Length of(RBSESolutions.com)rectangle (L) = 2x
Area of rectangle (A) = Length x Breadth
= 2x × x = 2x²
Table for x and corresponding A

 Breadth(x) 0 1 2 3 4 5 Area(A) 0 2 8 18 32 50

The graph is given below
