Question

Vince fenced both a square plot of side length 12.6 m and a rectangular plot of length 15 m and breadth 6 m in one day. How much did he earn that day if he charges $7 as the cost of fencing per meter?

Answer 1

Answer:

$646.8

Step-by-step explanation:

First ,

find the perimeter of the square and the rectangular plot.

perimeter of square = 4* a which equals to 4(12.6) = 50.4 m

Perimeter of rectangle = 2(l+b) which equals to 42 m.

Secondly,

Add both the perimeter i.e. 50.4 + 42 = 92.4 m.

Next use the unitary method.

1 m = $7

92.4 m = x

x = 92.4 * 7

x = $646.8

Answer 2

Answer:

$646.8

Step-by-step explanation:

find the perimeter of the square and the rectangular plot.

perimeter of square = 4* a which equals to 4(12.6) = 50.4 m

Perimeter of rectangle = 2(l+b) which equals to 42 m.

Secondly,

Add both the perimeter i.e. 50.4 + 42 = 92.4 m.

Next use the unitary method.

1 m = $7

92.4 m = x

x = 92.4 * 7

x = $646.8
