Finishing Profiles: Coordinates and Closing a Rectangular Path

Finishing Profiles: Coordinates and Closing a Rectangular Path

Original quantitative learning practice in English. All 24 questions are included. Four supplied cases exercise six related calculation targets; they form one topic, not four separate tests. Every question includes the complete initial data. Use the stated model and retain intermediate precision. Choose one answer. Learning target: 20/24, not an official pass mark. This bank covers the calculation topic in its title; it is not a complete professional examination, design approval or operating instruction.

A rectangular profile path starts at (0,0) mm, goes right 1400 mm, up 900 mm, left to x=0, then down to the start. A joint interrupts the first horizontal segment from x=220 to x=290; that interval contains no profile. There are 5 identical paths. Ignore corner fabrication allowances; use centreline lengths. Calculate the upper-right y coordinate in mm. Keep intermediate values unrounded; round the final result to four decimal places if necessary.
