Perimeter and Area 105

Let’s Attempt

Example 1: Find the area of the following figures by counting squares:

Solution: Figure Fully-filled More than Half-filled Less than Estimated area
squares (f) half-filled squares (h) half-filled h
squares (m) squares (l) f m 2

sq. units

(i) 10 0 2 0 11

(ii) 3 0 6 0 6
(iii) 2 2 2 2 5

(iv) 0 3 2 7 4

(v) 1 2 5 2 5.5
(vi) 4 4 1 10 8.5

Example 2: Find out the area of a rectangle of length = 5 cm and breadth = 3 cm.
Solution: Length = 5 cm, Breadth = 3 cm, Area = ?

\ Area = (length × breadth) sq units
2
= (5 × 3) cm = 15 cm 2
Example 3: A rectangular park is 25 m long and 15 m wide. Find its area.
Solution: Length of the park = 25 m

Breadth of the park = 15 m
Area of the park = length × breadth
2
= (25 × 15) m = 375 m 2
