Rectangle ABCD has vertices at A(-1,1), B(2,1), C(2,-5), and D(-1,-5). What is the perimeter of rectangle

The perimeter of the rectangle is 18 units.

Step-by-step explanation:

The image included below presents the location of the points on the Cartesian plane. From Geometry we get that the perimeter (), dimensionless, of the rectangle is the sum of its four sides. That is to say:

(1)

Where , , and are the sides of the rectangle, dimensionless.

Each side value is found by means of the Pythagorean Theorem:

And the perimeter of the rectangle is:

The perimeter of the rectangle is 18 units.

answer: no

step-by-step explanation: because the big angle will spread away the 2 side that it is on and make the opposite side even longer.

the correct answer option is d. la = πrs.

step-by-step explanation:

we know that for a right cone, the lateral surface area is given by:

lateral area of right cone =

here the value under the square root is equal to slant height so replacing this value by in the formula to get:

lateral area of right cone =

therefore, the correct answer option is d.
