Perimeter: 9+9+8+8= 34 ft.
Area: 9*8= 72 ft²
I believe the commutative property on multiplication

Answer:
i can,t see
Step-by-step explanation:
Answer : C
The perimeter is all the sides added up, lets check C.
C states that 2 sides have a measure of 9, and two sides have a measure of 4.
9+9 = 18 4+4 = 8
18+8 = 26
The question states that the perimeter is 26 so this makes sense, now lets check our area.
Area = width * length
9 * 4 = 36
The question states that the area must equal 36, and it does therefore you correct answer is C
Number 1 = 17
number 2 = 72
number 3 = 24
work:
the three numbers are symbolized as x, y, and z
x + y + z = 113
number 2 (y) is 3 times the third number (z) so
y = 3z
so x + 3z + z = 113
the first number (x) is 7 less than than the third number (z) so
x = z - 7
so z -7 + 3z + z = 113
5z - 7 = 113
5z = 120
z = 24
x = 17
y = 72
