Use the formulas for the area of a triangle and the area of a rectangle for both figures. The bases are the tops and bottoms of the figures and the lateral sides are the sides not including the top or bottom. It’s basically just finding the areas of each side and adding them all up to find the surface area. Volume is finding the area of the base, using the triangle area formula, and multiplying that by the height of the figure

Answer:4000
Step-by-step explanation:40 times 100 is 4000
To solve this problem, we must remember that there are 12 months in a year. To find the number of months in 3 years, we must multiply the number of months in a year (12) by the number of years (3).
12 * 3 = 36
Now, if we lease the car at $605 per month, we must multiply this number by the number of months leased (36) in order to find the total cost of the lease. Since this is an estimate, we can round 36 to 35 and $605 to $600 in order to make our computations easier.
$605 * 36 ≈ $600 * 35 = $21,000
Therefore, a good estimate for the lease is $21,000. If we want to check our work, we can always compute how much the lease would actually cost by solving $605 * 36 = $21,780. Because these two numbers are relatively close, we can infer that our estimate is reasonable.

75
----- = 0.75 The fraction 75/100 is equivalent to 3/4.
This is a proper fraction once the absolute value of the top number or numerator (75) is smaller than the absolute value of the bottom number or denomintor (100).
The fraction 75/100 is equal to 75÷100 and can also be expressed in decimal form as 0.75.
