Select the correct answer. What is the approximate perimeter of trapezoid DEFG? Round your answer to the nearest hundredth. A. 12 units B. 12.04 units C. 12.48 units D. 13 units

C. 12.48 units

Step-by-step explanation:

Perimeter of the trapezoid = DE + EF + FG + GD

DE = |-2 - 1| = 3 units

FG = |-3 - 2| = 5 units

Find EF and GD using distance formula

✔️Distance between E(1, 3) and F(2, 1):

Let,

(x1, y1) = (1, 3)

(x2, y2) = (2, 1)

Substitute

✔️Distance between G(-3, 1) and D(-2, 3):

Let,

(x1, y1) = (-3, 1)

(x2, y2) = (-2, 3)

Substitute

✅Perimeter = 3 + 2.24 + 5 + 2.24 = 12.48 units

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer

yes
