Method 1:
Considering the width and length of the quilt
Given

Required
Determine the dimension of 1 square
The width of the quilt is 4.5ft and there are 6 squares in that dimension.
Each measurement is calculated as thus:


Or
The length of the quilt is 3ft and there are 4 squares in that dimension.
Each measurement is calculated as thus:


Method 2:
Calculate the area of the quilt.


The area of 1 of the 24 squares is calculated by dividing the total area by number of squares


Represent the dimension of individual square with L
Area of a square is:

This gives:


Take square root of both sides


Hence, the dimension of each square is 0.75ft
