Elise planted a row of flowers in an area with the dimensions shown at the right. what is the area of her flower garden if the dimensions are 8ft by 1/2 ft?

Area is measured in square units such as square inches, square feet or square meters. To find the area of a rectangle, multiply the length by the width. The formula is: A = LW , where A is the area, L is the length, W is the width, 

A = ( 8ft) (1/2 ft)

A = 4 sq ft

Period is the time it takes for one “cycle” to complete. in the parent sine function, period is 2*pi since sin(0) = 0, sin(pi/2) = 1, sin(pi) = 0, sin(3pi/2) = -1, and sin(2pi) = 0. at that point, the sequence repeats itself. i’m not sure if your graph is similar to the sine function since you didn’t provide a picture, but you can find the period by looking at a graph.
