Answer:
x = 9
Step-by-step explanation:
You can solve this problem by isolating the variable.
3-√x = 0
√x = 3 (add √x to both sides of the equation)
x = 9 (square both sides of the equation)
the area is 180 cm. to find the perimeter you would do 15+15+14+14 to get 54 cm. So for area you do (l×w) which is 15×14=180.
