Answer:
Step-by-step explanation:
The length of the pool is 4 meters more than its width
Let x and (x + 4m) represent the width and length respectively
x(x+4m) = 192 m^2
solving for x
x^2 + 4m - 192 m^2 = 0
factoring
(x+16)(x-12)=0 |OR x+=+%28-4+%2B-+28%29%2F%282%29+ using Quadratic Formula
(x+16)=0 tossing out negative solution for measure
(x-12)=0 x = 12m, the width. The length is 16m (12m+4m)
