Problema Solution
A rectangle has an area of 12m and a width of 400cm. What is the length of the rectangle in meters
Answer provided by our tutors
Let 'l' and 'w' stand for the length and width of the rectangle. We can write:
Convert 'w' from cm to m:
w=(400cm)(1m/100cm)=4m
Area (we assume the problem means m^2)
Area=lw
12=l4
l=3m
