The height is 5 and 1/4 then the base is 2 and 1/2
You can convert these fractions into decimals and them multiply them to get your area.
Is there choices ? I got 0.216
the 2 angles are congruent so...
x+40=3x set the 2 equations equal to each other
40=2x subtract x from both sides
20=x divide by 2
x=20 is the final answer
Have a blessed day!
5.7 is your answer
Hope this helps.
