An expanding rectangle has a fixed width of 5 inches and an initial length of 0 inches. The length of the rectangle begins increasing at 2.3 inches per second. a. Write a formula that expresses the length of the rectangle, $l$ (in inches), in terms of the number of seconds, $t$, since the rectangle began growing. $l=$ b. Write a formula that expresses the perimeter of the rectangle, $P$ (in inches), in terms of the length of the rectangle, $l$ (in inches). $P=$ c. Write a formula that expresses the perimeter of the rectangle, $P$ (in inches), in terms of the number of seconds, $t$, since the rectangle began growing. $P=$ d. Suppose the function $g$ determines the perimeter of the rectangle (in inches) given a number of seconds, $t$, since the rectangle started growing. Write a function formula for $g$.
