Find the area of the trapezoid by decomposing into other shapes (explanation isnt needed unless you REALLY want to) Fast please first person right gets the brainliest!!!

99

Step-by-step explanation:

split into triangle + trapezoid

A of tri. = =3 * 6/2 = 18/2 = 9

A of trap. = =(10+20)(6)/2 = 90

add the two areas together

9+90 = 99

b. 24 mm

step-by-step explanation:

use the pythagorean theorem.

a^2 + b^2 = c^2

a^2 + 7^2 = 25^2

a^2 + 49 = 625

a^2 = 576

a = 24

answer: b. 24 mm

a is the right answer
