Answer:

Saw this question before. The answer is Anita' square.

Square has only four sides while the others more than four so make sense for the square to have longer sides

The length of a rectangle is three times its width of the perimeter of the rectangle is 40 yd find its length and width
schepotkina [342]

Answer:

Step-by-step explanation:

L= 3W

Perimeter = 2(l+w) = 40

 

2(3w+w) = 40

 

2*4w = 40

8w =40

w = 5

l = 3*5 = 15

Find the coordinates of G if F(2,5) is the midpoint of line GJ and J and has coordinates (-2,8)
dimulka [17.4K]

Answer:

G(6,2)

Step-by-step explanation:

If point F(x_F,y_F) is the midpoint of the segment GJ, where G(x_G,y_G) and J(x_J,y_J), then

x_F=\dfrac{x_G+x_J}{2},\\ \\y_F=\dfrac{y_G+y_J}{2}.

In your case,

F(2,5),\ J(-2,8),

therefore,

2=\dfrac{x_G+(-2)}{2},\\ \\5=\dfrac{y_G+8}{2}.

Thus,

x_G-2=4\Rightarrow x_G=6,\\ \\y_G+8=10\Rightarrow y_G=2.

Perimeter = w + w + l + l
180= w+w+w+12+w+12
The dimensions for width are just w and for length it's w+12
