Question

a concrete strip boder is placed and the perimeter of the garden. calculate the length of the strip boder that is required.

Answer 1

Here the dimensions or shape of the garden is not given.

But no matter what the shape and dimensions are " The length of the strip of concrete border is equal to the perimeter of the garden "

For example :-

1. If the shape of garden is CIRCULAR with radius 5 metres , then Length of the strip = Circumference

  Length of the strip = 10π metres.

2. If the shape of garden is RECTANGULAR with dimesnions 10m*20m , then Length of the strip = Perimeter

  Length of the strip = 2*(10+20)

  Length of the strip = 60 metres.

Similarly, in every case " LENGTH OF CONCRETE STRIP = PERIMETER OF GARDEN " .
