Question

application to principal to attend marriage ​

Answer 1

Step-by-step explanation:

if x is the side/dimension of a square then its

area=x²

perimeter=4x

(a)16cm area=16²=256cm²

perimeter=4a=4(16)=64cm

(b) 5.3m area=5.3²=28.09m²

perimeter=4(5.3)=21.2m

(c) 2 m 37cm=2.37m

area=2.37²=5.6169m²

perimeter=4(2.37)=9.48

(d) 86dm means 86 decimeters

1decimeter=0.1 meter

then 86dm = 86x0.1m=8.6m

area=8.6²=73.96m²

perimeter=4(8.6)=34.4m
