Answer:
L = 10, W = 6
Step-by-step explanation:
(x-2)(x+2) = 60
[tex]x^{2}[/tex] - [tex]2^{2}[/tex] = 60
[tex]x^{2}[/tex] = 60 + 4 = 64
x = [tex]\sqrt{64}[/tex] = 8 or -8
-8 rejected
thus length is 8 + 2 = 10, width is 8-2=6
The length is 10 units and width is 6 units.
Length = x+2
Width = x-2
Area = 60
Area = Length × Width
Therefore, (x+2)(x-2) = 60
x²-2x+2x - 4 = 60
Collect like terms
x² = 60+4.
x² = 64.
Therefore, in order to get the value of x, we'll find the square root of 64
x² = 64.
x = ✓64
x = 8
Length = = x+2 = 8+2 = 10
Width = x-2 = 8-2 = 6
In conclusion, the length is 10 units and width is 6 units.
