You need to first draw the diagram then you must determine your two formulas of area and perimeter like #=2L+2W and #=L•W and then you can use substitution from one formula to solve a single variable in the other formula.

Can you find the perimeter if you know area of a rectangle?

You can find the perimeter of a rectangle if you know its area and the length of one side. Divide the area by the length of the known side and the quotient will be the length of a side perpendicular to the known side, and then multiply the sum of the two sides by two to find the perimeter.


How you find the area of a rectangle from the perimeter and base length?

perimeter (P)=2(length+base) find length, area = length * base = (p/2-base)*base

How do you find the area and the perimeter of a rectagle?

To find the area of a rectangle, you multiply the width by the length. Area=width multiplied by length. To find the perimeter of a rectangle, you can either add all four sides of the rectangle together (p=w+w+l+l), or find the length and width of the rectangle and multiply that by 2 (p=2(w+l)). You can also find the perimeter by multiplying the width by 2 and the length by 2 and then adding those together (p=2w+2l).


How do you find the perimeter and area and formula on a rectangle?

for area you multiply length times width and for perimeter you add all of the sides together


How do you find the area from the perimeter of a rectangle?

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 unit 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.+++To summarise, you can, IF you know the ratio as mentioned. Then apply that to half the perimeter to find the length and breadth.
