Video Solution

Solution Steps

00:00 Calculate the area of deltoid ADEF
00:06 According to the given data, CB equals twice the height
00:10 Substitute in the relevant value and calculate CB
00:24 FD is the middle segment, therefore it equals half of the base (CB)
00:28 Substitute in the relevant values to determine FD
00:35 Apply the formula to calculate the deltoid area
00:42 (diagonal(AE) x diagonal(FD)) divided by 2
00:46 Substitute in the relevant values and proceed to solve
00:51 This is the solution

Answer

8 cm²
