The length of the remaining piece of board will be 2 feet 3 inches.
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.
