The dimensions of a rectangular plank are 6.7 m x 85 cm. Find its perimeter (in m) and area (in sq. m.).

Since opening night, attendance at play a has increased steadily, while attendance at play b first rose and then fell. equations modeling the daily attendance y at each play are shown below, where x is the number of days since opening night. on what day(s) was the attendance the same at both plays? what was the attendance? play a: y = 8x + 191 play b: y = -x^2 + 26x + 126

How to do this , and can some one explain

Is the figure congruent? yes or no?
