All the questions please

Answer 1

a) area of parellogram = base x altitude
= 8.3 x 4.5
=37.35 cm^2
b) base = 2.5 m
altitude =850 cm = 850/100 m = 8.5m
area of ||gm = 2.5 x 8.5 =21.25 m^2

c) base = 4 dm
altitude = 4dm 5cm
we know ,
1 dm = 10 cm
so,
altitude = 4.5 dm
now ,
area of || gm = 4 x 4.5 = 18 dm^2

e) base = 6 dam
altitude = 15m

we know ,
1 dam = 10 m

so,
base = 60 m
altitude = 15 m

area of || gm =60 x 15 = 900 m^2

now,
we also know ,
1 are = 100 m^2

so,
area of ||gm = 900/100 = 9 ares
