Questions:-

Find the area of a rectangle whose :

(i) length = 12 cm and breadth = 6 cm

(ii) length = 1.4 m and breadth = 0.5 m

(iii) length = 3 m and breadth = 80 cm

(iv) length = 15 cm and breadth = 130 mm

Answers:

We know that,

✤ Area of rectangle = l × b ✤

In which,

• l is length of rectangle.
• b is. Breadth of rectangle.

(i) Length = 12 cm and breadth = 6 cm

Area of rectangle = 12 × 6

= 72

Area of rectangle is 72 cm².

________________________

(ii) Length = 1.4 m and breadth = 0.5 m

Area of rectangle = 1.4 × 05

= 0.7

Area of rectangle is 0.7 m².

________________________

(iii) Length = 3 m and breadth = 80 cm

Length of rectangle = 3 × 100= 300 cm 【1 m = 100 cm】

Area of rectangle = 300 × 80

= 24000

Area of rectangle is 24000 cm².

________________________

(iv) Length =15 cm and Breadth = 130 mm

Length of rectangle = 15 × 10 = 150 cm 【1 cm= 10mm】

Area of rectangle = 150 × 130

=19500

Area of rectangle is 19500 mm².
