Question

A table top measure 2 m 15 cm by 1 m 45 cm. Find its perimeter.

Answer 1

perimeter of table (rectangle) = 2(L+B)
= 2(2.15+1.45)
= 2(3.60)
= 7.20 m

Answer 2

perimeter of a rectangle= 2*(l+b)
so we have
length=2.15 cm
and breadth= 1.45
.
. . l=215 cm
and b =145cm

2*(215+145)
2* 360
720 cm
