Using the formula for area for a parallelogram, A=BH, where A is area, B is Base, and H is height, you follow that. So in this case, you would want to find one of the area's then multiply it by 4. So for the area you get 20.52 meters. If you multiply it by 4, you get 82.08 meters. Have a nice day!
Number of boxes = 3 across x 4 deep = 12 total boxes.
Each box has 6 tissues.
Total tissues = 6 per box x 12 boxes = 72 tissues.
This problem is an another case which makes use of the concept of ratio and proportion. The ratio $2.52 per 0.5 gal should be proportional to the price of 4 gallons of milk. Let x be the price,
($2.52 / 0.5 gallon) = (x / 4 gallons)
The value of x is 20.16. Hence, the price of 4 gallons of organic milk is $20.16.
