Area in square units = base*height

If the only information that you have is ... A) the figure is a rectangle, and B) the perimeter ... then you cannot calculate the area. The area of a rectangle is the length multiplied by the height., The perimeter is twice the length plus twice the height. So, a rectangle with a length of 9 units and a height of 1 until will have a perimeter of 20 units and an area of 9 square units. Another rectangle with a length of 6 units and a height of 4 units will also have a perimeter of 20 units, but it will have an area of 24 square units. To be able to calculate the area from the perimeter you need to know one of two additional things - either one of the measurements, or the ratio of the height to the length.

Length multiplied by width.It is length times height calculated in square units

Then apply that to half the perimeter to find the length and breadth.

a rectangle has a length of 2x-5 units and a width of x-3 units. what is the area, in square units, of the rectangle?

Area of a rectangle in square units = length*width

The area of rectangle is : 35.0

42 square units.

Multiply the length by the wide. eg a 3cm x 6cm rectangle - 3x6=18sqcm The answer is in square units, - square feet, metres, mm etc
