Question

A rectangle whose length =30 cm and breadth = 0.2 m.
​

Answer 1

Answer:

100cm

Step by step explanation

0.2m=20cm

Perimeter=2(l+b)

=2(30+20)

=2×50

=100cm

Answer 2

Length = 30 cm

Breadth = 0.2 m or 20 cm

Perimeter = 2(length + breadth)

= {2(30 + 20)} cm

= {2 × 50} cm

= 100 cm

Area = length × breadth

= (30 × 20) cm²

= 600 cm²
