Answer 1

Explanation:

i’m doing my geometry homework with the equation 1/2h(b1+b2) but i can’t figure this one out. please help

1/2h (b1 + b2) is the formula for finding the area of ​​the figure (trapezoid)

1/2 * 12 (18 + 5 + 12)=

6 * 35=

210 units²

Answer 2

Explanation:

to find the bottom base you add the two numbers that make it

5+18=23

now put everything in the formula

`(1)/(2)*12(12+23)\\`

parathesis first

12+23=35

`(1)/(2) *12*35`

multiply in order

6*35

210
