Question

The length and breath of a rectangular playground are 11dm and 76m respectively. find the length of wire needed to fence around the playground five times.

Answer 1

----------------------------------------

Here is the solution:

----------------------------------------

Convert units to m:

11dm = 1.1 m

Find the perimeter:

Perimeter = 2(Length + breadth)

Perimeter = 2(1.1 + 76 ) = 154.2 m

Find the length of the wire:

one round = 154.2 m

5 rounds = 154.2 x 5 = 771 m

Answer: The length of the wire is 771m

Answer 2

#AlexaRousey here!!

Since Perimeter of playground = 2(l+b)

=2(76m + 1.1dm)

= 2(76 + 11(0.1)) m

= 2(77.1)m.

= 154.2 m.

Length of wire to fence around playground five times = 5(154.2 m.)

= 771m.
