A square piece of fabric is the side length of 3.2 cm find the area of the piece of the fabric
Sauron [17]

The area of square fabric piece is 10.24 cm^2

Step-by-step explanation:

Square is a four-sided shape where all sides are equal. The area of square is calculated by using its side.

Given

Side length of fabric piece = s = 3.2 cm

The area of square is given by:

Area = A = s^2

Putting s= 3.2

Area = (3.2)^2\\= 10.24\ cm^2

Hence,

The area of square fabric piece is 10.24 cm^2

Keywords: Square, area

Need help with these 2 please

1) given that those two lines are parallel, we can deduce that 9/45=x/75. 
9/45 simplifies to 1/5 so 1/5 = x/75. Cross multiply to get this: 5x = 75.
Divide both sides by 5 to get x.
Final answer: x = 15

2) Again, we can set up a proportion to solve for x because we know the lines are parallel. 24/36=x/12. 24/36 simplifies to 2/3 so 2/3=x/12. Cross multiply to get this: 3x = 24. Divide both sides by 3 to get x.
Final answer: x = 8
