need tile for L shape floor-- 6th grade math?

Question

measurements of floor---76 ft. at bottom--40 ft. left side--38ft. top go down 12 ft. right side is 20 ft. cost tile is 1.19 how many tiles and what will be the cost.

sorry the tile is 1 ft.sq. he took and squared the floor by 76x40 then took off the 12 ft. down

Answer 1

Your numbers don't add up... and you haven't specified the dimensions of the tiles (are they 1 sq. ft.?)

Generally, when you have an L-shaped room, break it into two rectangles. Figure the area of the two rectangles using:
A = L x W

Add the two together and that is your total square footage.
Finally multiply this by your tile price (assuming they are 1 sq. ft.) to get the total cost.

For example, let's assume the dimensions were 76' along the bottom, 40' on the left, 38' at the top, *20'* down, over another 38' and then down 20'.

Then you have two rectangles:
40' by 38' and 20' by 38'

The areas are:
40 x 38 = 1,520 sq. ft.
20 x 38 = 760 sq. ft

Total is 2,280 sq. ft.

Multiply this by $1.19 per sq. foot

2,280 x 1.19 = $2,713.20

Or if your dimensions were: 76' along the bottom, 40' on the left, 38' at the top, 12' down, over another 38' and then down *28'*, then you have the following two rectangles:
40' by 38' and 28' by 38'

The areas are:
40 x 38 = 1,520 sq. ft.
28 x 38 = 1,064 sq. ft

Total is 2,584 sq. ft.

Multiply this by $1.19 per sq. foot

25,84 x 1.19 = $3,074.96

Answer 2

Your dimensions so not add up. If the left side is 40 feet, then 12 + right side must = 40 so right side = 28, not 12.Assuming you meant 28 feet, the answer is 38*40 +38*28 = 2548 ft^2.

If you meant to go down 20 feet instead of 12 feet, the answer is 38*40+38*20 = 38*60 = 2280 ft^2

Assuming the tiles are 1 foot squares, you will need either
2548 or 2280 tiles. Cost will be $3,032.12 or$2713.20
with the assumption that the units of 1.19 is dollars.

Answer 3

Yeah what he said
