Question

on square bcde if e is located at (4,-9) and d is located at (10,-5) find the perimeter of the square

Answer 1

• 8
  `√(13)` units

Explanation:

We know that:

• P = 4a

We can find one side by distance formula:

• a =
  `√((x_2-x_1)^2+(y_2-y_1)^2)`
• a =
  `√((10 - 4)^2+(-5+9)^2) = √(36+16) = √(52) = 2√(13)`

Then the perimeter is:

• P = 4*2
  `√(13)` = 8
  `√(13)` units
