Question

Hi I don't know how to do this question

Answer 1

Answer:

7 (option B)

Step-by-step explanation:

the area of a trapezoid can be found using the formula:

$A = \frac{a+b}{2}h$

where

A: area

a: base

b: other base

h: height

here, we can plug in our known variables to solve for h (height)

A: 119

a: 10

b: 24

h: ??

$A = \frac{a+b}{2}h$

$119 = \frac{10+24}{2}h$

{now, simplify!}

$119 = \frac{10+24}{2}h$         {add 10 + 24}

$119 = \frac{34}{2}h$            {divide 34 by 2}

119 = 17 · h

119     =    17 · h

÷ 17       ÷17             {divide both sides by 17to isolate h}

7 = h

So, the height (h) of this trapezoid is 7

hope this helps! have a lovely day :)
