A = 2(bh/2) + 2lw + bw

2(bh/2) comes from the area of one triangle being bh/2 and there are two triangles (so we multiply bh/2 by 2)

2lw comes from the areas of the 2 rectangle faces

bw comes from the third rectangular face

A = 2(bh/2) + 2lw + bw
A = bh + 2lw + bw
(If you multiple then divide a number by the same thing, you end up getting the same number you started with)
A = (24cm)(5cm) + 2(13cm)(10cm) + (24cm)(10cm)
A = 120cm^2 + 260cm^2 + 240cm^2
A = 620cm^2

Hope this helps!

What is the finance charge on 13,300 financed at 7.9 percent for 4 years if the monthly payment per 100 is 2.74?

Julli [10]

To answer this question we have to first determine how many times 100 can go into 13,300. To find this we do the following:

$13,300/$100 = 133

Now we simply multiply the result by $2.74:

$2.74*133 = $364.42.

Finally we just multiply that by the total number of payments which are (monthly payment, 12 months in a year, for 4 years).

$364.42*(12*4) ---> $364.42*48 = $17,492.16.

The correct answer is choice 4.) 17,492.16

I hope this helps, Regards.
