Answer:
Perimeter ABCD = 6.082762530 x 4 = 24.3 cm unit (24.33 to 4sf)
AD = AC = √37 = 6.1cm
BD = 8.6cm units
AM = BM = CM = DM
8.6 / 2 = 4.3 cm units
Explanation:
AD = 6^2 + 1^2 = c^2
√36 + √1 = c^2
c^2 = √37 = 6.082762530
AD = 6.1 cm units
CD = 6^2 + 1^2 = c^2
√36 + √1 = c^2
c^2 = √37 = 6.082762530
CD = 6.1 cm units
Perimeter = 6.082762530 x 4 = 24.3310501 cm unit
BD = AC Diagonal therefore would be congruent in cm length.
BD = 6.082762530 ^2 + 6.082762530^2 = c^2
√37 + √37 = c^2
c^2 = √74 = 8.60232527
BD = 8.6cm units
AM = BM = CM = DM
8.6 / 2 = 4.3 cm units
