118 feet perimeter.
Sides MN and ML = 2x + 10
Sides NO and LO = 4x - 17
You can therefore write this equation:
118 = 2(2x + 10) + 2(4x - 17)
Now let's solve for x.
118 = 4x + 20 + 8x - 34
118 = 12x - 14
132 = 12x
/12 /12
11 = x
Now substitute.
Sides MN and ML = 2x + 10 = 2(11) + 10 = 22 + 10 = 32 feet.
Sides NO and LO = 4x - 17 = 4(11) - 17 = 44 - 17 = 27 feet.
Those are your measurements.
Proof: 2(32) + 2(27) = 64 + 54 = 118.
