You are cutting a rectangle piece of fabric in half along the diagonal.The fabric measures 19 inches wide and 5 yards long. What
cestrela7 [59]

Given,

Length of the rectangle piece of fabric, l = 5 yards

Width of the rectangular piece of fabric, b = 19 inches

To find,

The length of the diagonal.

Solution,

The relation between Yards and inches is :

1 Yard = 36 inches

5 yards = 180 inches

Let x be the diagonal. It can be calculated as :

x=\sqrt{l^2+b^2} \\\\x=\sqrt{180^2+19^2} \\\\x=181\ inches

Hence, the length of the diagonal is 181 inches
