Please help! One problem need to solve: Find the area of trapezoid with bases 7cm and 20cm and diagonals 13cm and 5√10 How calculate height of trapezoid without area? Or how calculate the area if I have only two bases and two diagonals? But without length of non-parallel sides, or without height I can't find area. Maybe is another way to solve.? Replay please...
