Warm-up

Redimensionemos una habitación

Este es un dibujo a escala de una habitación. El dibujo tiene la siguiente escala:

1 unidad en el dibujo representa 4 pies en la habitación real.

Calcula el área de la habitación real. Prepárate para explicar tu razonamiento.

An irregular hexagon with five sides with labeled lengths. Going clockwise beginning at the top the sides are: a 3 unit horizontal line, a 1 unit vertical line, a 2.83 unit diagonal line to the right, a 1 unit vertical line, a 5 unit horizontal line (this is the bottom of the shape), and a 4 unit vertical line connecting back to the beginning.
