Question

find the perimeter of rectangle whose length=6.46cm and its breadth = 36mm

Answer 1

Perimetre of rectangle =2(l+b)
1 cm=10mm .So 6.46cm =64.6mm
=2(36+64.6)mm
=2×100.6mm
=201.2mm

Answer 2

length = 6.46cm
= 6.46×10 mm
=64.6 mm
breadth=36 mm
Perimeter = 2 (Length + Breadth)
=2 (64.6+36 mm)
=2 (100.6 mm )
=201.2 mm
