A table-top measures 2 m 25 cm by 1 m 50 cm. What is the perimeter of the top of the table-top?

It is given in the question that,

Length of table top, l = 2 m 25 cm


= 2 + 0.25 (Because 25 cm = 0.25m)


= 2.25m


Also,


Breadth of the table top, b = 1 m 50 cm


= 1 + 0.50 (Because 50 cm = 0.50m)


= 1.50 m


We know that,


Perimeter of table-top = 2 (l + b)


= 2 (2.25 + 1.50)


= 2 × 3.75


= 7.5 m


Hence, perimeter of table-top is 7.5 m
