• A. $270m$
• B. $230m$
• C. $540m$
• D. None

Answer 1

Answer: (C)

$540m$

Given that, a playground which is $250m$ long and $20m$ wide is fenced with wire.

To find out: The amount of wire.

Amount of wire needed $=$ Perimeter of a rectangle = $2\times (length+breadth)$

Hence, wire needed $=$ $2\times (250+20)$

$=$ $540m$

Hence, the amount of wire required to fence the playground is $540m$.
