1cm^2=1cm
1m^2=1m
so 5A=145
50B=900
(let A and B be the lenght)
so A=29cm
B=18cm

平方米=1m乘1m
A)Ax5cm=145cm2, A=145cm2/5cm=29cm
B)50MxB=900M2,B=900M2/50=18
平方米=1m乘1m
A)Ax5cm=145cm2, A=145cm2/5cm=29cm
B)50MxB=900M2,B=900M2/50=18

A) A x 5cm = 145cm2, A = 145cm2 / 5cm = 29cm
B) 50M x B = 900M2, B = 900M2 / 50M = 18M
cm是厘米, cm2是平方厘米
M是米, M2是平方米
希望你明白
B) 50M x B = 900M2, B = 900M2 / 50M = 18M
