Area of Bottom Rectangle: 12 in X 8 in = 96 in^2

Area of Top Rectangle: 13 in X 8 in = 104 in^2

Area of Side Rectangle: 5 in X 8 in = 40 in^2

Area of Side Triangle: (5 in X 12 in)/2 = (60)/2 = 30 in^2

So total surface area = 96 + 104 + 40 + 2(30) = 300 in^2

Answer:

y=1.5x+2.5

Step-by-step explanation:

First you find the slope:

$\frac{7-4}{3-1}$ or $\frac{3}{2}$

lets change it into 1.5

Then write it in point-slope: (I used (1,4))

y-4=1.5(x-1)

y-4=1.5x-1.5

y=1.5x+2.5

Answer:

.55

Step-by-step explanation:

You want to shorten the decimal to just to two after the decimal point. If so for example, .443 would be shortened to .44, but if the third number is 5 and up, you would take the second number after the decimal point and add 1. For example,

.446 would round up to .44, which is why .5524 would round to .55
