Can someone help before I have a breakdown I’ve been trying to get this for a hour now

c = 29

Step-by-step explanation:

Alright, So from the numbers, we know each side is 7

So overall area is 49

And each triangle is 5(5 x 2/2)

And multiply that by 4 to get 20

49 - 20 is 29

 the length of c is √29

Step-by-step explanation:

The Pythagorean Theorem states that "The square on the hypotenuse is equal to the sum of the squares on the opposite sides."

The formula looks like c² = a² + b²

To apply that here, "c" is the hypotenuse of the right triangle that has "2" and "5" as the opposite sides. We can consider 2 as side a, and 5 as side b.

Square each of those numbers, then add them together.

2² means 2×2=4  and 5² is 5×5=25   4+25 = 29

Now we go into reverse to get the value of c.  We have c²=29

So we take the square root of 29  c=√29

That is an "irrational" number, meaning it is not a whole number or a fraction. So we can get an approximate value by using a calculator. (Nowadays! Back in the day, there was a nice long paper and pencil procedure. . .)

√29 is about 5.385164807  and it keeps going. Just round it off!

(Some math teachers are fine with leaving the irrational roots as √something)

Apparently, the green answer box for this question needs √29

But it helps if you can associate some nearly rational value to make sense of it.

But you know the length of c should be about 5.39. It makes sense if you were to measure the sides with a ruler.

what i would say the best answer is a. 40.5
