Answer :
Let the breadth be x
length=x+8
according to the question
area of the pool = l*b
105=x*x+8
if u solve this equation further u will get the answer
length=x+8
according to the question
area of the pool = l*b
105=x*x+8
if u solve this equation further u will get the answer
length = w + 8 and width = w and A = 105
A = W* L
105 =w(w + 8)
105 = w² + 8w
0 = w² + 8w - 105
0 = (w + 15)(w -7)
0 = w + 15 or 0 = w -7
w = -15 or w = 7
width cant be negative, so
w = 7 and L = 7 +8
w = 7 and L = 15
7 * 15 = 105 check
