Answer:

perimeter of square = 35.78 cm

Step-by-step explanation:

cut the rhombus into 4 triangles along the diagonals

each triangle has a base of 5 and a height of 10 cm

area of one triangle = 1/2(4)(10) = 20 cm^2

4 triangles = area of rhombus = 80 cm^2

then the square has an area of 80 cm^2 also

side^2 = 80 cm^2

side of square  = 8.94 cm

perimeter = 8.98 x 4 = 35.78 cm

What is the distance between begin ordered pair 8 comma negative 3 comma 4 end ordered pair and begin ordered pair 6 comma negat
katen-ka-za [31]

Answer:

d = \sqrt{14} = 3.74...

Step-by-step explanation:

To find the distance between (8, -3, 4) and (6, -4, 1), use the distance formula for (x,y,z) points. It is very similar to (x,y) points.

d = \sqrt{(x_2-x_1)^2 + (y_2-y_1)^2 + (z_2 - z_1)^2} \\d = \sqrt{(8 - 6)^2 + (-3--4)^2 + (4-1)^2} \\d = \sqrt{(2)^2 + (1)^2 + (3)^2} \\d = \sqrt{4 + 1 + 9}\\ d = \sqrt{14} = 3.74...
