Shikaku: Paper & Ink Logic

One number, one rectangle's area, exactly one solution. Calm Japanese logic with no timer and nothing to lose.

Draw a rectangle around each number so its area matches. There is exactly one way.

Every cell ends up covered, none of them twice. Shikaku is a Japanese logic puzzle with no timer, no lives, and nothing to lose. Drag a box; if it is not right yet, leave it — a half-finished rectangle is a note to yourself, and it costs nothing.
