Step-by-step explanation:
I calculated logically
Answer:
x =2
Option D is correct !!!
Step-by-step explanation:
By Pythagoras theorem we can solve this
we know that:




For every side you just add 90 to your equation. so #4 would be 360-125-125-55=(55)
First calculate the area of the pool, which is 15 x 15, = 225 sq meter,
and just multiply the cost for each sq meter by the area,
17.5 x 225
therefore the cost will be $3937.5
First you'll need to find the area of each side and then add those areas together. 2(6x10)+2(4x6)+2(4x10)= 120+48+80=248
then you multiply the total area by .25 and get 62. It will cost $62.
