Add together all the sides... i.e. Area(rectangle) = 2(l+w)
You simply have to measure all the sides of the oblong and add them together. If the opposite sides of it are equal (making it a rectangle), then you just need to measure the two different sides and add them together, then multiplying the result by 2. perimeter = a + b + c +d or perimeter = 2(a+b)
the measure for a regular rectangle is 69in. by fudge you and measure it yourself.
You can measure it.
is the perimeter of the triangle whose sides measure 7.5 7.1 and 8.1
perimeter is the measure around the figure; area is the measure within the figure formula: perimeter: length+length+width+width=perimeter (for square or rectangle) area: length times width= area ( for square or rectangle)
Yes.
Perimeter is the sum of the measures of the side lengths. A rectangle with length 15 and width 7 has two sides that measure 15 and two that measure 7. So 7 + 7 + 15 + 15 = 44 is the perimeter.
1.) You can measure the sides of the shapes and add
Measure and add together the 4 sides
Yes. The perimeter is a measure of the combined length of all the sides. If you double the lengths of the sides then naturally this will also necessarilychange the perimeter (it will double the perimeter).

The area cannot be 15 feet since that is a measure of length, not area. In any case, information about the area cannot determine the perimeter; it can only put a lower limit on it. The perimeter can be anyhting from 15.49193 ft upwards. Consider the following rectangles, all with area = 15 square feet: a sqrt(15)*sqrt(15) rectangle will have a perimeter of 4*sqrt(15) = 15.49193 ft (approx). 1ft*15ft rectangle will have a perimeter of 32 feet 0.1ft*150ft rectangle: perimeter = 300.2 feet 0.01ft*1500ft rectangle: perimeter = 3000.02 ft 0.001ft*15000ft rectangle: perimeter = 30000.002 ft by now you should see that there is no upper limit to the perimeter.
Add together all the sides... i.e. Area(rectangle) = 2(l+w)
You multiply the length by 2 (because there are two sides of the rectangle that have that measure). You then subtract that number from the perimeter. The number you will be left with is twice the width, so you divide that by two and you get the width of the rectangle.
Since the only number given in the question is a linear measure, it must refer to the perimeter of the rectangle: it cannot refer to its area. So, number of feet of fencing required to enclose a rectangle with a 44 ft perimeter is 44 ft! That is what a perimeter means!
Do you mean the perimeter?? If so, that involves adding up the length of all four sides :)
