Answer:
52 ft
Step-by-step explanation:
area of a square is l x w. all sides are equal so the l = w
A = 169 ft^2 so each side is the square root of 169 which is 13 ft
perimeter of the floor would be all four sides added or length of 1 side multiplied by 4 since they are all equal
Perimeter = 13ft × 4 = 52 ft
so:
Answer:
x=4 and x= - 5
Step-by-step explanation:
In order to solve this we should re-arrange the equation:

This is equal to:

Then we can seperate this into:

So solving for x in both cases we get

You will get r= 21/12 but you have to simplify to get R=7/4 or R=1.75
