Answer:
25.2X + 3.4 centimeters.
Step-by-step explanation:
The formula for the perimeter of a rectangle
= 2L + 2W
= 2(L + W)
From the question:
Width of a rectangle (W) = 9.7 X - 4.7 centimeters
Length of a rectangle (L) = 2.9 X + 6.4 centimeters
Imputing it into the formula
2(L + W)
2( 9.7X - 4.7 + 2.9X + 6.4)
2 (9.7X + 2.9X - 4.7 + 6.4)
2( 12.6X + 1.7)
= 25.2X + 3.4 centimeters.
Therefore, the perimeter of the rectangle = 25.2X + 3.4 centimeters.
