Question 1.

Find out the length of the boundary (i.e., the perimeter), of each of the other arrangements below. Class 6

Arrange the two pieces to form a figure with a perimeter of 22 cm.

Solution:

(b) Perimeter = (2 + 6 + 2 + 6 + 2 + 4 + 6) cm = 28 cm.

(c) Perimeter = (6 + 2 + 2 + 6 + 2 + 6 + 2 + 2) cm = 28 cm.

(d) Perimeter = (6 + 2 + 3 + 2 + 6 + 2 + 3 + 2) cm = 26 cm.

For perimeter of 22 cm, two pieces may be arranged as follows :

Its perimeter = (6 + 2 + 1 + 2 + 6 + 2 + 1 + 2) cm = 22 cm.

Question 1.

The area of a rectangular garden 25 m long is 300 sQuestion m. What is the width of the garden? Class 6

Solution:

Width of the garden = [latex]\frac{\text { Area }}{\text { Length }}[/latex]

= [latex]\frac{300}{25}[/latex] m = 12 m.
