Question

How do you do this???

Answer 1

Answer:

There are two unknown lengths that we need to find.

The upwards rectangle intersecting with the horizontal rectangle's inner side lengths would be;

28ft(total length) - 12ft(one given side length of different rectangle)

= 16 feet.

Now the horizontal rectangle's inner length that intersects with the upwards rectangle would be;

40ft(total length) - 12ft(one given side of different rectangle)

= 28 feet.

Now add all the lengths:

12 + 40 + 28 + 12 + 16 + 28

= 136 feet is the perimeter of the swimming pool.

Now they want us to find the total cost it would take to place tiles that cover one yard.

We first convert the feet into yards knowing that;

1 yard = 3 feet.

136(perimeter in feet)/3 feet(which make up a single yard)

= 45.333... which can be rounded to 45.3, so the perimeter of the pool in yards is 45.3.

Now since each of those yards contains $15, we multiply the many yards that cover the perimeter of the pool by the cost of one tile.

45.3 x 15

= 679.5, so it would cost approximately $679.50 to place tiles along the pool.

Answer 2

12+28+40+12=52
Perimiter =52ft

Yards=3 feet
52ft/3 is about 17.34yards
Now multiply yards by cost
17.34 x 15=260$
It costs 260 for titles to be put around the pool
