Question

PLEASE HELP ME

The swimming pool at Spring Valley High School is a rectangle with a width of 70 meters and a length of 30 meters. Around the perimeter of the pool is a tiled floor that extends w meters from the pool on all sides. Find an expression for the area of the tiled floor.

Answer 1

ans - option 4.

first find the perimeter:

70 + 70 + 30 + 30 = 140 + 60 = 200

expression for tiles:

we know that the area of the tiled floor will extend through all 4 sides of the rectangular pool, so we would multiply w^2 (an area of 1 side) by 4 which is 4w^

therefore, the answer is 4w^2 + 200w. Option 4.
