The diagonals for a parallelogram have lengths of 8 and 11. Find the area and perimeter if the diagonals create a 138 degree angle

perimeter is 42.19 () and area is 10.5475 x 2 = 21.0950 () ^2

Step-by-step explanation:

138-180 = 180-42 = 138angle either side so the relation is 8x11 x2 and 126 makes half 4x4.5 so the extra 12 is 12/138/2 = 12.5% = 6.25% of 8x11 = 0.5 + 0.6875 + 4x4.5=5.36+5.1875 = 10.5475 x 4=42.19
