it says draw a rectangle with a perimeter of 15 units.
wat would be the the length/width of each sides then?
please help!

Perimeter means the total of all the measures of each side. So, you just need to find 4 measurements that equal 15. Since this is a rectangle, each opposite side will measure the same.
There are a few different answers for this. For example, 2 of the sides could measure 6 units (for a total of 12) and the other 2 sides would measure 1.5 units (for a total of 3). This would give you a grand total of 15 units.

Please forgive me if I'm stating the obvious but from your question it's possible that you are not sure what 'perimeter' is. It's simply the length of the sides added together. So if the perimeter is 15 units then 2 of the sides must add up to 7.5 units. So basically, you can pick any 2 numbers for the length and width that add up to 7.5
4.5 and 3
4 and 3.5
6.8 and 0.7 etc.

If it replaced right into a trapezoid, which could be very superb. For a rectangle it really is likewise genuine, yet considering a rectangle has 2 equivalent widths and a couple of equivalent facets, a more suitable useful equation may be; 2 X width + 2 X length = perimeter. (for a rectangle)

There would be a number of answers.
First of all if you divide 15 by 2 =7.5 and so 7.5 must be the sum of the rectangles length and breadth.
So it could be 1 unit wide and 6.5 units long =7.5 and x 2 =15
Or it coud be 3 units wide and 4.5 units long =7.5 and x 2 =15
As you can see there are other combinations which give 7.5x2=15

a rectangle has opposite sides equal.
perimeter of rectangle=2(length+width) =15
so by taking length+width= 7.5; in one of many different ways you can draw the rectangle.
eg., length =4, width =3.5 or
length =2.5, width =5

Your L = 4m
Your W = 3.5m
Because Perimeter of a Rectangle = 2(L + B).

This is not hard, think outside the box, or rectangle in this case. You need two the same and two more the same, and they add to 15, ie 2x5 and 2x2.5

there are infinite answers since
2* length + 2* breadth = 15, there is only one equation , to find two unknowns , u need two equations

Length=x units
Width=y units
2(x+y)=15
2x+2y=15
2x=15-2y
x=7.5-y(0

2.5, 2.5, 5, 5.
This is one combination.
3, 3, 4.5, 4.5 is another.....and so forth.
