Question

The length of a rectangular playground is three times its width. If a boy walks around the ground, he covers 160m. Find its length and Width​

Answer 1

⚝Solution:-

• Let the Width be x
• Then the length=3x

Perimeter=2(Length+Breadth)

➯160=2(3x+x)

➯160=2(4x)

➯160=8x

➯160/8=x

➯20=x

then Width=20 metre

Length=3×20=60 metre

Answer 2

Let width be x

Length=3x

=perimeter=2(l+b)

=160=2(3x+x)

=160=8x

=160/8=x

=width=20=x

=length=3×20=60
