altitude or height =20cm
area =0.8m=80 cm square
1/2 × 20×b=80 Sq. cm
b =80/10 =8 cm.
area =0.8m=80 cm square
1/2 × 20×b=80 Sq. cm
b =80/10 =8 cm.

area of triangle=1/2xbxh
0.8m square=1/2xbx20/100
=0.8x2x100/20=base
=0.8x10=base
=base=8m
I placed 100 as denominator because 20 was in cm.And area was in m.
0.8m square=1/2xbx20/100
=0.8x2x100/20=base
=0.8x10=base
=base=8m
I placed 100 as denominator because 20 was in cm.And area was in m.

8m
OK. . .
8m is same as 800cm . 1m =100cm
is that clear
but you know very well that area is in m.
so it depends upon you that you will change it in cm or not.
Now is that clear
yah but height is in cm
that's why I changed the height into m
OK ok
