Step-by-step explanation:
To solve this, we need to know the total share which is,
Then, you need to know the fraction of the share over the total, such that
So if to find how much that'll be of the $180 for the largest and smallest share,

Sal will pay $77.78 to tile his entryway
<h3><em><u>SOLUTION:</u></em></h3>The image of the question is attached below.
Given each unit length = 1 foot
Tile cost per square feet = $1. 65
To find the area, split the floor shape into two shape.
One is trapezoid and the other is parallelogram.
Let's count the grid given.
The parallels sides of trapezoid are 7 ft and 4 ft, height is 7 ft.
The base and height of the parallelogram are 4 ft and 4 ft respectively.
Area of the trapezoid =1/2 ×(sum or parallel sides)× height
=1/2× (7+4)×5
=1/2×11×5
Area of the trapezoid = 27.5 sq.ft
Area of the parallelogram = base × height
= 4 ft × 4 ft
Area of the parallelogram = 16 sq. ft
Total area = 27.5 sq. ft + 16 sq. ft
= 43.5 sq. ft
Cost of area per sq. ft = $1.65
Cost of area 43.5 sq. ft = 43. 5 × 1.65
= $71.775
= $71.78
Hence Sal will pay $71.78 to tile his entryway.
