Find the surface area. Do not round your answer

1,672.6

Step-by-step explanation:

In order to find the surface area of a figure, you must first find all the bases you must find the area for. You must find the areas of two pentagons and five rectangles.

We know that the area of the base is 386.3. That means that the area of one pentagon is 386.3. We can multiply that value by 2 in order to find the area of both pentagons. That gets you 772.6.

Now, we have to find the areas of the five rectangles. Luckily, they're all the same size, so we can use the expression a=bh or 12x15 to find the area of one rectangle. That gets you 180. Now, multiply that by 5 in order to find the area of all the rectangles. That gets you 900.

Now, add the two areas together (bolded for clarity) to get the surface area.

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet

ok then what happened.
