Question 8

Match the following:

Shapes Perimeter A 4 (i) 10 (ii) 18 B 5 Square Equilateral Triangle (iii) 20 D

Answer 1

(iii) Here, length = 6 and breadth = 4
$\therefore$ Perimeter of a rectangle = 2$\times$(6+4) = 2$\times$10 = 20

(iii) Here, side = 5
$\therefore$ Perimeter of a square = 4$\times$Side = 4$\times$5 = 20

(ii) Here, side =6
$\therefore$ Perimeter of an equilateral triangle = 3$\times$Length of a side = 3$\times$6 = 18

(i) Given sides are 4, 4 and 2.
$\therefore$ Perimeter of an isosceles triangle = Sum of all sides = 4 + 4 + 2 = 10
