1)t=S/U=2.4/12=0.2
2)t=S/U=8.4/36=0,23
3)0.23-0.2=0.03

Answer:
A pair of inverse operations is defined as two operations that will be performed on a number or. variable, that always results in the original number or variable. Another way to think of this is. that the two inverse operations “undo” each other.

Answer:
the perimeter of a square = 28 feet.
the area of a square = 49 ft²
Step-by-step explanation:
given:
side length of a square = 7 feet.
find:
perimeter (P) of a square
area (A) of a square
<u>Perimeter of a square = 4s</u>
P = 4(7)
P = 28 feet.
<u>area of a square = s²</u>
A = 7²
A = 49 ft²
therefore,
the perimeter of a square = 28 feet.
the area of a square = 49 ft²
