Question

Find the perimeter of the rectangle,length=3.5 meter,width=70 centimeter​

Answer 1

Answer:

width= 70cm= 70÷100= 7/10m

length= 3.5 m

perimeter of rectangle = 2(l+b)

=2(3.5+7/10)

=2×42/10

=42/5 m

Answer 2

Length =3.5m, breadth =70 cm=0.7m

Perimeter=2(l+b)

=2(3.5+0.7)

=2(4.2)

=8.4m

Hence, answer is 8.4m
