I have two simple problems that i can't solve.

1. The diagonal of a rectangle is 15 cm, and the perimeter is 38 cm. What is the area? Is it possible to find the area without finding the dimensions of the rectangle.

The area is 68. But I wouldn't have been able to get it without the dimensions.

2.Dissect a 1-by-3 rectangle into three pieces that can be reassembled into a square.
