100 - (5+d)×2
That's what my teacher told me.
Answer:
x = 0.75 feet
Step-by-step explanation:
The area of a square is 18/32 square foot
We need to find the side length of the square.
The area of a square of side x is given by :
Substitute all the values,
So, the side length of the square is equal to 0.75 feet.
The perimeter of a rectangle is - 2 x (length + breadth).
Also, 1 feet = 12 inches.
So, the dimensions of the tablecloth are 108 inches long by 72 inches wide. So, the total perimeter of the table cloth is --> 2 x (108 + 72) = 360 inches.
So, time taken for 1 tablecloth = 360 x 3 = 1080 minutes.
And, Time taken for 2 tablecloths = 1080 x 2 = 2160 minutes.
So, to complete her sewing project, Frances will take a total of 2160 minutes (36 hours).
