The length of the remaining piece of board will be 2 feet 3 inches.
What is an expression?
Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
It is given that Donny had a 10-foot board. He used the board to make two shelves. One shelf measured 4 feet 7 inches wide and the other shelf measured 3 feet 2 inches wide.
The length of the remaining part is calculated as below:-
10 foot = 10 x 12 = 120 inches
4 feet 7 inches = (4 x 12) + 7 = 48 + 7 = 55 inches
3 feet 2 inches = ( 3 x 12 ) +2 = 36 + 2 = 38 inches
Remaining length = 120 - 55 - 38 = 27 inches
= 24 + 3 = 2 feet 3 inches.
Therefore, the length of the remaining piece of board will be 2 feet 3 inches.
