Solution
Length (l)
of table-top = 2 m 25 cm = 2 + 0.25 = 2.25 m
Breadth
(b) of table-top = 1 m 50 cm = 1 + 0.50 = 1 .50 m
Perimeter
of table-top = 2 (l + b)
= 2 × (2.25 + 1.50)
= 2 × 3.75 = 7.5 m
Length (l) of table-top = 2 m 25 cm = 2 + 0.25 = 2.25 m
Breadth (b) of table-top = 1 m 50 cm = 1 + 0.50 = 1 .50 m
Perimeter of table-top = 2 (l + b)
= 2 × (2.25 + 1.50)
= 2 × 3.75 = 7.5 m
