The height is 6tan(60)=10.39 then plug that in to trapezoid area formula
(11+6+15)/2*10.39=166.24
D + 1.5......with d being the price of a smoothie.....the expression would represent the total cost of one smoothie + one sandwich.
Width of the rectangle is x + 3 in
Step-by-step explanation:
- Step 1: Given area of the rectangle = 3x² + 9x in². Length = 3x in. Find width.
