Afarm is to be built in the shape of quadrilateral abcd, as shown below. all four sides are equal. what is the area of the farm? (1 point) select one: a. 62 square feet b. 52.8 square feet c. 57.4 square feet d. 102.3 square feet 15.5 ft acroos top 13.2 ft top to bottom

b

step-by-step explanation:

answer: it's d

step-by-step explanation:

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
