The lengths of the diagonals of a rhombus are 4x and 6x. What expressions give the perimeter and area of the rhombus? PLEASE HELP

Area = 12x²

Perimeter = 4x√13

Step-by-step explanation:

Formula to be used for the area of a rhombus,

Area =

        =

        =

Since, diagonals of a rhombus bisect each other at 90°.

OD =

      =

      = 2x

AO =

      =

      = 3x

By using Pythagoras theorem in ΔAOD,

AD² = AO² + DO²

AD² = (2x)² + (3x)²

AD² = 13x²

AD = x√13

Perimeter of a rhombus = 4(Side)

                                        = 4(x√13)

                                        = 4x√13

answer: 230 miles ( vote ! )

step-by-step explanation:

180.39 minus 17.99 equals 162.4

then divide 162.4 by .80 to get 230
