Diện tích khu đất là:
1/4x1/8=1/32 (km)2
Chu vi khu đất là:
(1/4+1/8)x2=3/4 (km)
(k cko mk nhe^^)
Chu vi khu dat hinh chu nhat la
[1/4+1/8]*2=3/8
Dien h la ;
1/4*1/8=1/32
S=\(\frac{1}{4}\times\frac{1}{8}=\frac{1}{32}\)(\(km^2\)) V=(\(\frac{1}{4}+\frac{1}{8}\))x2=\(\frac{3}{4}\)(km)
S = \(\frac{1}{4}\times\frac{1}{8}=\frac{1}{32}\) km2
Chu vi = \(\left(\frac{1}{4}+\frac{1}{8}\right)\times2=\frac{24}{32}=\frac{6}{8}=\frac{3}{4}=0,75km\)
