Question

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

Answer 1

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

$L= 5 \frac{1}{2}W= 3 \frac{1}{2}$

Perimeter = $2( 5 \frac{1}{2}+3 \frac{1}{2} )=2(\frac{11}{2}+\frac{7}{2} )=2(\frac{18}{2} )=2(9)=18$

Perimeter of rectangular is 18m

Answer 2

2·51/2 + 2·31/2 = 82 m

2·(5 + 1/2) + 2·(3 + 1/2) = 18 m
