Total length of tape required = Perimeter of rectangle
= 2 ( length + breadth)
= 2 ( 40 + 10)
= 2 x 50
= 100 cm = 1 m
Thus, the total length of tape required is 100 cm or 1 m.

Length (l) of rectangular box = 40 cm
Breadth (b) of rectangular box = 10 cm
Length o f tape required = perimeter of rectangular box
= 2 ( l + b)
= 2(40 + 10) = 100 cm
