Her total bill is $186 because :
(3x39)+15+(2x27)
60/25 = 12/Y
cross multiply and divide
25 x 12 = 300
300 / 60 = 5
Y = 5 boxes
Answer:
39 units²
Step-by-step explanation:
A line segment from R to V will divide the figure into a 5 by 6 rectangle and a triangle with base 6 and height 3. Appropriate area formulas will help you find the areas of these parts. The total area is the area of the parts.
rectangle area = L·W = 5·6 = 30 . . . units²
triangle area = 1/2·b·h = 1/2·6·3 = 9 . . . units²
Then the polygon area is ...
polygon area = rectangle area + triangle area = (30 +9) units² = 39 units²
