Find the area of the rectangle whose dimensions are:
(i) length = 24.5 m, breadth = 18 m
(ii) length = 12.5 m, breadth - 8 dm.
ANSWER:
(i) Length = 24.5 m
Breadth = 18 m
∴ Area of the rectangle = Length ×
Breadth
= 24.5 m ×
18 m
= 441 m2
(ii) Length = 12.5 m
Breadth = 8 dm = (8 ×
10) = 80 cm = 0.8 m [since 1 dm = 10 cm and 1 m = 100 cm]
∴ Area of the rectangle = Length ×
Breadth
= 12.5 m ×
0.8 m
= 10 m2
(i) length = 24.5 m, breadth = 18 m
(ii) length = 12.5 m, breadth - 8 dm.
ANSWER:
(i) Length = 24.5 m
Breadth = 18 m
∴ Area of the rectangle = Length ×
Breadth
