What is that area of the trapezoid
a) 175in

b)140in

c)129in

b)85

C

Step-by-step explanation:

(b) 140 in

Step-by-step explanation:

by the formula (a + b)/2 × h

where a = 15

b = 15 + 4 + 6 =25

h = 7

(15 + 25)/2 × 7

40/2 × 7

20 × 7

140

the answer is b: 18

step-by-step explanation:

use the pythagorean theorem to .

a^2+b^2=c^2

plug 18 for "r"

the 2 legs are 18 and 24

18^2+24^2=c^2

324+576=c^2

900=c^2

c=30

30-12=18

18 is the radius
