67.5 degrees
3pi/8 * 180/pi = 67.5
Rachel needs 1776 inches of board
<em><u>Solution:</u></em>
Given that, Rachel is making a planter box
Her box measures 345 inches long and 543 inches wide
Length = 345 inches
Width = 543 inches
<em><u>To find: Inches of board she needs</u></em>
So we need to find the perimeter of the board
The board is usually of rectangular shape
<em><u>Perimeter of rectangle is given as:</u></em>
Perimeter = 2(length + width)
Perimeter = 2(345 + 543)
Perimeter = 2(888)
Perimeter = 1776
Thus she needs 1776 inches of board
7.8456 x 10^(-4)
this means you move the decimal place to the left 4 places to get the actual value
