The dimensions of the rectangular pool shown below are 40 yards by 20
yards. a fence will be built around the outside of the deck. the ratio of the
dimensions of the fence to the dimensions of the pool is how many yards
of fence should be purchased to enclose the deck?
a. 60 yards
b. 180 yards
c. 120 yards
d. 1200 yards

Option C. We need to put 120 yards of fence around the pool.

Solution:

Given that, The length and breadth of the rectangle pool are 40 and 20 yards.

We need to put fence around the pool.  The measure of the fence will be equal to the perimeter of the pool.  The formula for the perimeter of the rectangle is

Here l is the length; b is the breadth.

On substituting the values, we get the perimeter of the rectangle.

Therefore, Perimeter .

So, we need to put 120 yards of fence around the pool.

600-28w < 300

600-28w > 300

im sorry but no. i just need to answer for 50 poonts oof
