If you let the width be x, then the length will be 2x + 3. The perimeter P is
twice the width plus twice the length, i.e.,
P = 2*x + 2*(2x + 3) = 2x + 4x + 6 = 6x + 6.
So if the perimeter is 66 cm then 66 = 6x + 6 ---> 6x = 60 ---> x = 10 cm.,
and so if the perimeter is at most 66 cm., the width can be at most 10 cm..
The box is 5m long, 3m wide, 4m high
An exterior angle equals the sum of the remote interior angles
.
So
x + 60 = 95
x = 95 - 60
x = 35
Answer
B. 35
