IQR is the Q3 - Q1
Put the data in order.....
6, 7, 11, 13, 14, 15, 15, 19, 21
^ ^ ^
9(Q1) 14(Q2) 17(Q3)
17 (Q3) - 9 (Q1) = 8 (IQR)
So the answer to your question is the first option, 8.
Hope this helps! :D

Answer:
Step-by-step explanation:
Find the area of each shape, then multiply by 20, then round to nearest hundred.
Half circle:
=πr²/2
=50π
=157.08
Large square:
=L•w
=20(22)
=440
Small square:
=L(w)
=12(3)
=36
Triangle:
=b(h)/2
=8(3)/2
=12
Btu req:
=(157.08+440+36+12)(20)
=(645.08)(20)
=12901.6
=12900 BTU
