"A linear equation is an equation in which the highest power of the variable is always 1. It is also known as a one-degree equation. The standard form of a linear equation in one variable is of the form Ax + B = 0. Here, x is a variable, 'A' is a coefficient and 'B' is constant".
Here, 7 yards 2 feet 8 inches plus 4 yards 3 feet 7 inches
= (7 + 4) yards (2 + 3) feet (8 + 7) inches
= 11 yards 5 feet 15 inches
= 11 yards (5 + 1) feet (15 - 12) inches
= 11 yards 6 feet 3 inches
= (11 + 2) yards (6 - 6) feet 3 inches
= 13 feet 3 inches
