Question

Find the perimeter of the polygon with vertices of A(0, 0), B(4, 0) and C(2, 3). Round to the nearest tenth. Just enter one number as your answer

Can you please help me

Answer 1

A - B = 4
A - C = sqrt(4+9)
B - C = sqrt (4+9)

4 + 2 sqrt (13)

Answer 2

but my homework just wants one number as an answer not the square roots

Answer 3

use the distance formula to get the lengths of the sides:

4,√(2^2+3^2),√(2^2+3^2)

so the perimeter is 4+2√13

Answer 4

so use your calculator to evaluate 4+2√13

geez...

Answer 5

would the answer be 11.21

Answer 6

It says to nearest tenth, not hundredth
11.2
