Question

when students enter the library they are able to walk anywhere in the library where a bookcase is not present all for bookcases are the same size a diagram below shows the dimensions of the library bookcases what is the area in square feet the available carpet for students to walk

Answer 1

4 rectangles each of dimensions 6ft by 2.5ft: Area of bookcases = 4(L x B) = 4(6x2.5) = 4x15 = 60 square feet

Area of the library = L x B = 40 x 17 = 680 square feet

Area of available carpet to walk on = Area of the library - Area of bookcases = 680 - 60 = 620 square feet
