El largo de un terreno rectangular es 42 cm más que dos veces su ancho. El perímetro es
624 cm.

Ancho:   x

Largo:  2x + 4  

PERÍMETRO DEL RECTÁNGULO:

                        P = 2(Largo) + 2(Ancho)

luego pasa por este:

          32 = 2(2x + 4) + 2x

          32 = 4x + 8 + 2x

          32 = 6x + 8

     32 - 8 = 6x

          24 = 6x

       24/6 = x

            4 = x

Lo cambias por este:

Ancho:   x = 4 pies

Largo:  2x + 4 pies = 2(4 pies) + 4 pies = 12 pies es de PERRITOS1000

Step-by-step explanation:

18

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.
