Abigail is putting tiles on a table top. She needs 48 tiles for each of 8 rows. Each row will have 6 white tiles.
almond37 [142]
I think its like this 
each row has 6 white tiles
8 rows = 48 tiles 
48 - 6 = 42
42 x 8 = 336
so 8 rows = 6 white tiles and 42 purple tiles to make 48 tiles so she will need 336 more tiles to make each 8 rows have 48 tiles

hope this helps : )

Answer:

77.74 square feet

Step-by-step explanation:

1. We have to keep the triangle and the rectangle apart and find the area of each separately then add the areas together.

The formula for the area of a rectangle is height x width = area

So, 6.5 feet x 10.4 feet = 67.6 feet squared

The formula for the area of a triangle is height x width x (1/2) = area

So, 5.2 feet x 3.9 feet x (1/2) = 10.14 feet squared

Now, add the two areas together.

10.14 square feet + 67.6 square feet = 77.74 square feet
