Area of rectangular room = length * breadth. it is measured in square units.
Metres and centimetres. Or feet and inches. Then square any measurements to find the area.
in area you are measuring the capacity. Volume has a 3 because it is lengthxwidthxhight area is only lengthxwidthImproved Answer:Because the perimeter is the outside measurements of a given area which are in linear units and the measurements inside a given area are in square units.
Area is measured in square units.
The units are incompatible. Metres mare a unit of linear measure. Square units are for measuring area.
14.28 cm2Multiply length by width to get area: 3.4 x 4.2 = 14.28. The answer will be in units of cm x cm = cm2.
A rectangular area 9 units by 7 units has an area of 63 square units.
You always use square units when measuring area.
Area in square units = length*width
Square metre.
Surface area is measured in square units.
The area of rectangle is : 2106.0
A frame measuring 9 units by 11 units will have an exact area of 99 units.
Area = 10*20 = 200 square units
The total area would become 32*344 = 3096 square units.
432 square units.
If you are referring to a rectangular prism then the surface area = 594 square units.
