area = 1/2 × product of diagonals so area = 1/2 × 30 ×16 = 240 cm² also diagonals bisect each other at right angles so 1/2×30= 15cm,,,, 1/2×16 =8cm therefore by Pythagoras theorem, 15² + 8² = side² √289 = side side = 17 cm thus perimeter = 4 × 17 = 68 cm

area = 1/2 × product of diagonals
so area = 1/2 × 30 ×16 = 240 cm²

also diagonals bisect each other at right angles
so 1/2×30= 15cm,,,, 1/2×16 =8cm

therefore by Pythagoras theorem,
15² + 8² = side²
√289 = side
side = 17 cm

thus perimeter = 4 × 17 = 68 cm
