Let w be the width then w+4 is the length and 2*w+2*(w+4)=4*w+8 is the expression for the perimeter. So
4*w+8>=48
4*w>=40
w>=10

7.2 x 10 - 6 = 72 - 6 = 66
3.09 x 103 = 318.27
2.04 x 104 = 212.16
5 x 103 = 309
3.09 x 103 is the largest
The number of unit squares with a side length of 1/10 foot that Rhys uses to tile the rectangle is 24 units
<h3>How to calculate the area of plane shapes?</h3>
A square is a plane shape with 4 sides
The formula for calculating the area of the square is expressed as:
A = l^2
Given
side length of a square = 1/10 foot
A = (1/10)² = 1/100 = 0.01 square foot
<u>Determine the area of the rectangle</u>
Area = length * width
Area = 3/10 * 4/5
Area = 12/50 = 6/25
Area = 0.24 square foot
<u>Take the ratio of both areas</u>
Ratio = 0.24/0.01
Ratio = 24 units
Hence the number of unit squares with a side length of 1/10 foot that Rhys uses to tile the rectangle is 24 units
