Question

A rectangular swimming pool measures 51/2 metres by31/2 metres. what is the perimeter

Answer 1

2·51/2 + 2·31/2 = 82 m

2·(5 + 1/2) + 2·(3 + 1/2) = 18 m

Answer 2

Perimeter is the sum of all the sides for any figure.

In a rectangle opposite sides are equal .If the length and width of rectangle are l and w then Perimeter = 2(l+w)

In the given question

`L= 5 (1)/(2)W= 3 (1)/(2)`

Perimeter =
`2( 5 (1)/(2)+3 (1)/(2) )=2((11)/(2)+(7)/(2) )=2((18)/(2) )=2(9)=18`

Perimeter of rectangular is 18m
