Question

find the perimeter,area and diagonal of a square each of whose measures

i)16cm
ii)8.5m
iii)2.5dm

Answer 1

1:answer is
156 area
54perimeter
2 diagonals

Answer 2

perimeter of a square = 4×side
diagonal of a square= sqroot 2 × length of side
And area = (side)^2
hence
(1)side =16 cm
perimeter=4×16=64cm
digonal=16sqrt2
area =(16)^2=256cm^2
(2)side=8.5m
perimeter =4×8.5=34m
area=(8.5)^2=72.25m^2
diagonal=8.5×sqroot2m
(3)side=2.5dm
perimeter=4×2.5=10dm
area=(2.5)^2=6.25dm^2
diagonal=2.5× sqroot2dm
