Talulah drew the net shown on a piece of cardboard. She plans to cut it out to make an odd-shaped gift box.
The pattern has three rectangles side by side. The shorter side of the rectangles is 3 c-m, the lengths of rectangles are 4 c-m, 3 c-m, and 5 c-m respectively. The middle rectangle has a right triangle above it and a right triangle below it. The measurements of the right triangle are 3 c-m, 4 c-m, and 5 c-m.
