The equation that calculates the unknown side length, L of the rectangular logo is A = 3.1L
The height (H) of the logo is given as:
H = 3 1/10 feet
Let the area of the logo be A
The area (A) of a rectangle logo is the products of the dimensions.
So, we have:
A = LH
Substitute 3 1/10 for H
A = L * 3 1/10
Express the fraction as decimal
A = L * 3.1
This gives
A = 3.1L
Hence, the equation that could be used to determine the unknown side length, L of the logo is A = 3.1L
