A table-top measures 2 m 25 cm by 1 m 50 cm. What is the perimeter of the table-top?
Answer:
Length of the table-top = 2 m 25 cm = 2 m + 25 cm = 2 m +
m
= 2 m + 0.25 m = 2.25 m
Breadth of the table top = 1 m 50 cm = 1 m + 50 cm = 1 m +
m
= 1 m + 0.50 m = 1.50 m
Perimeter of the table top = 2(length + breadth) = 2(2.25 + 1.50) = 2(3.75) = 7.50 m
