Question

What is the surface area of this figure?

B = 21

P= 21
147 i n to the power of 2


357 i n to the power of 2

1459.5 i n to the power of 2

24.95 i n to the power of 2

Answer 1

Going to share an image of this figure?

Answer 2

sorry one sec

Answer 4

Assume that you need to find the TOTAL surface area.

You have two triangular ends, each of base 7 and height 6; find the area of one such triangle and multiply that by 2.

You have two sides, each of width 5 and length 6.95; find the area of one and multiply that by 2.

You have one base whose measurements are 5 by 7; calculate that area.

Then add all 3 results together.

Answer 9

We don't give answers here. we help.

This problem can be broken down into several simple steps.

Do you know how to find the area of a rectangle?

Answer 10

yes but ive been waiting too long and now I have like 3 minutes left

Answer 11

We'll go quickly.

The bottom rectangle is 7 in. by 5 in.: 7 x 5 =
The right rectangle is 5 in. by 6.95 in.: 5 x 6.95 =
The left rectangle is 5 in. by 6.95 in. 5 X 6.95 =

Do that first, then we'll do the two triangles.

Answer 12

For the two triangles, they are of equal; dimensions, so we calculate the area of one and multiply by 2.

A = base * height /2

A = 7 in. * 6 in. /2 =
Calculate the area of the triangle above and multiply by 2.

Answer 13

Then add all areas together.

Answer 14

i got the second choice am i right

Answer 15

I don't get any of the choices. I get 146.5 in^2

Answer 16

It's closest to the first one.

Answer 17

then the closest one would be 140

Answer 18

Where do you see 140? I see 147 as the first choice

Answer 19

oh right sorry
