To work out the area or perimeter of any compound shape, split the shape so that you are left with regular shapes e.g. for 9b split the shape and you will get two rectangles
Then you can easily work the area/perimeter of the shapes you made and add them up
Hope this helps :)
No, if Cole can only painting half a room in one day it would take him 2 days to paint a whole room therefore in 7 days he'll only have painted 3.5 rooms, not 7 rooms. Maybe he needs some help

a cup detergent for

Rounding is when you have at least a two digit number (26 for example) and if the number the right (6) is 5 or above then the number goes up one unit, (therefore 26 becomes 27). But if the number (22) to the right is 4 or lower, then the number to the right stays the same, but the number to the right becomes a zero, (making 22 now 20).
(Btw that’s not 50 points, imma solve this for you because you’re desperate)
Using the Pythagorean theorem:
c^2 = a^2 + b^2
c^2 = 4^2 + 7^2
c^2 = 16 + 49
c^2 = 65
c = 8.1
