Answer:

y=2, x=4

Step-by-step explanation:

sin60=2sqrt3/x

so x = 2sqrt3/sin60

and x=4

for the value of y, use pythagorean theorem to get

16=y^2+12

which gives you y=2

How to find Lateral area of this rectangular prism??<br><br>Plzz help me it is due tomorrow!!
yaroslaw [1]

Answer:

132 square millimeters

Step-by-step explanation:

THe <u>lateral area</u> of a rectangular prism is the side areas. That is

all 4 sides of the rectangular prism (that are rectangles each).

So, we find each side area and add them up.

The area of a rectangle is:

Area = length * width

The left side (in gray) is 9 mm x 3mm, so area:

area = 9 * 3 = 27

The right side rectangle is same, so that would have an area of:

area = 9 * 3 = 27

Now, the front side's measurement is 3 x 13, so the area is:

Area = 3 * 13 = 39

THe back is same, so the area would be:

Area = 3 * 13 = 39

<u>Total Surface Area = 27 + 27 + 39 + 39 = 132 square millimeters</u>
