Grade 6

Perimeter and Area of Plane Figures | Exercise 32(B)

Question 1

Q1) Find the area of a rectangle whose :

(i) length = 15 cm breadth = 6.4 cm

(ii) Length = 8.5 m breadth = 5 m

(iii) Length = 3.6 m breadth = 90 cm

(iv) Length = 24 cm breadth =180 mm

Solution 1:

(i) Area = 15 × 6.4 cm square

= 96 cm square

(ii) Area = 8.5 × 5 metre square

= 42.5 metre square

(iii) USING. 1 metre = 100 centi metre

90 cm in metre = 0.9 m

Area = 0.9 × 3.6 metre square

= 3.24 metre square

(iv) l = 24 cm

b = 180 mm

USING 1 centi metre = 10 mm

b in cm = 18 centi metre

Area = 24 × 18 cm square

= 432 cm square
