Answer: Either 28in or 26in

A table cloth 40 inches squared could be 1 by 40, 2 by 20, 4 by 10, 5 by 8

1 by 40 would have a perimeter of 1(2) + 40(2) = 82in

2 by 20 would have a perimeter of 2(2) + 20(2) = 44in

4 by 10 would have a perimeter of 4(2) + 10(2) = 28in

5 by 8 would have a perimeter of 5(2) + 8(2) = 26in

1 by 40, and 2 by 20 are highly unlikely table cloths so it is either 26in or 28in

Answer:

8√(10)

Step-by-step explanation:

The area of a square is given by the formula

A = s²

Since the area is 40, that gives us

40 = s²

Take the square root of each side:

√(40) = √(s²)

√(4*10) = s

2√(10) = s

Since each side of a square is the same length, this makes the perimeter

2√(10)+2√(10)+2(√10)+2(√10) = 8√(10)

<span>B) (1, 5) is your best answer

B (0,6) creates the top of the kite
D (0,2) creates the bottom
A (-1,5) creates the left side of the kite
D (1,5) creates the right side (only the x is flipped, because has congruent sides of both the top, and both the bottom.
