Answer: the width of the rectangle
= 31feet.
Step-by-step explanation:
Perimeter of a triangle = 2( l + b)
let the width = xfeet
The length = 2x feet.
Substitute for this in the equation above,
2( 2x + x ) = 186
2(3x) = 186
Divide by 2 through
3x = 93
Divide by 3
x = 31feet. Therefore, the width of the rectangular = 31feet.
Check.
Since the length is twice the width,
L = 31 x 2
= 62feet.
Put that into the formula above
2( 62 + 31 )
2 x 93
= 186 which is the perimeter of the rectangle.
x - y = 8
Add y to both sides
x = 8 + y
4x + y = 4
Substitute the value of x from the first equation in
4(8 + y) + y = 4
Simplify and solve
32 + 4y + y = 4
32 + 5y = 4
5y = -28
y = -5.6
Now put that value of y into the first equation
x = 8 + (-5.6)
x = 2.4
