Question 835411: find the area in square meters of a piece of cardboard 1m 25cm wide and 2m long

You can put this solution on YOUR website!
area = length * width
For this problem,
area = ( 1m 25 cm )*(2m)
Since we want our final answer in m%5E2,
we need to represent 1m 25cm in terms of meters only.
25cm = 0.25m so 1m 25m = (1 + 0.25)m = 1.25m
and
area = %28+1.25+%29%282%29m%5E2
area = +%282.5%29+m%5E2
