Perimeter ?
I am in 5class
what is the answer ​

Answer 1

Answer:

4008 cm

Step-by-step explanation:

Length of a rectangle = 4 cm

Breadth = 20 m = 2000 cm

∴ Perimeter = 2 × (L+B) = 2 × (4+2000) cm = (2×2004) cm = 4008 cm

Answer: Perimeter = 4008 cm

Answer 2

length = 5 cm

breadth = 20 cm

perimeter = 2(L+B)

= 2(4 + x )

= 2 (4x)

x = 2/4

x = 2

therefore , breadth of rectangle = 2m .
