Wall A's area is easy to find. Just multiply the length and the width. For the others, try and divide the rectangles into small pieces. With those small pieces, find the area as well. Then, add the areas to find the total area that needs to be covered in paint.
But I don't know how to get wall 2 and 4
I don't get the question. sorry.
I need to find the area of the walls in the picture
wall 1 A = 9 * 18
Its 162ft right? And wall 3 is 134ft
Wall 2 A = 21*9 - 7*5
wall 3 A = 18*9 - 7*4
Wall 4 A = 21*9 - 4*3
That was step 1 the next step says what is the total area that we need to cover with paint? Do I just add all of those areas together then? Or is there something else I feel like im over analyzing this. @DanJS
