Answer:
Width = 5 ft
Step-by-step explanation:
A=wl
10 = wl
24 inches = 2 ft
10 = 

Answer:
Because 5+5=10 and 7+7=14
94.1224489795918367 is the answer to your question
Area = length *width
A = x²
3x² = (x+10)(x+12)
3x² = x²+10x+12x+120
3x² = x²+22x+120
3x²-3x² = x²+22x+120-3x²
0 = -2x²+22x+120
Factor to solve for x:
-2(x²-11x-60)
(x+4)(x-15)
x = -4 & x = 15 but we can't have a negative length so we eliminate 4. The length of the square is 15 cm.
