First of all, let's remember the formula for calculating area. <em><u>Length times width equals area.</u></em> (lxw=a)
Now that we have the formula. Let's take the length (8 cm) and the width (6 cm) and add 1 cm to each of them.
Length: 8+1=9.
Width: 6+1=7.
Now, let's apply the formula for area.
9 x 7 = 63
Now that we've found the area is 63 cm, let's find the perimeter. To find the perimeter of a rectangle, we must multiply the length by 2 and the width by 2, then we add the two numbers. In this case, here's what we'll do:
9 x 2 = 18
7 x 2 = 14
18 + 14 = 32
Now we have the area and perimeter.
Final answer(s):
Area = 63 cm.
Perimeter = 32 cm.
Hope this explanation helped you out. :)

Answer: he would have $13134 at the end of 10 years
Step-by-step explanation:
The formula for continuously compounded interest is
A = P x e (r x t)
Where
A represents the future value of the investment after t years.
P represents the present value or initial amount invested
r represents the interest rate
t represents the time in years for which the investment was made.
e is the mathematical constant approximated as 2.7183.
From the information given,
P = $9000
r = 3.79% = 3.78/100 = 0.0378
t = 10 years
Therefore,
A = 9000 x 2.7183^(0.0378 x 10)
A = 9000 x 2.7183^(0.378)
A = $13134 to the nearest dollar
Basically, this problem wants you to solve the area of the trapezoid given those dimensions, then multiply this to the unit cost to determine the total cost. The formula for the area of trapezoid is written below:
A = (a+b)h/2, where a and b are the lengths of the two bases
A = (15+9)(10)/2 = 120 cm²
Total Cost = 120 cm² * $0.80/cm² = <em>$96</em>
