A park is mapped on a coordinate plane, where C1, C2, C3, and C4 represent chairs and SW1, SW2, and SW3 represent swings. How fa
serg [7]

Answer:

Option (B)

Step-by-step explanation:

To calculate the distance between C2 and SW1 we will use the formula of distance between two points (x_1,y_1) and (x_2,y_2).

d = \sqrt{(x_2-x_1)^{2}+(y_2-y_1)^2 }

Coordinates representing positions of C2 and SW1 are (2, 2) and (-6, -7) respectively.

By substituting these coordinates in the formula,

Distance between these points = \sqrt{(-6-2)^2+(-7-2)^2}

                                                     = \sqrt{(64)+(81)}

                                                     = \sqrt{145} units

Therefore, Option (B) will be the correct option.

256 + 324 = x^2

x^2 = 580

x is about 24.08.
