Answer 1

Answer:

Step-by-step explanation:

as the area of rectangle is given by

Area = Length x Breadth

1) Area = 30 x 16 = 480 $cm^{2}$

2) Area = 20.5 x 10 = 205 $cm^{2}$

3) Area = 12 x 6 = 72 $m^{2}$

Hope this helps

Answer 2

Answer:

(i) Length = 30 cm

Breadth = 16 cm

Area=L X B

Area = 30cm X 16 cm

Area = 480cm2

(ii) Length = 20.5 cm

Breadth = 10 cm

Area = L X B

Area = 20.5 cm X 10 cm

Area = 205 cm2

(iii) Length = 12m

Breadth = 6m

Area = L X B

Area = 12m X 6m

Area = 72 m2
