A rectangle has four sides, where the opposite sides are equal
The possible coordinates are: (-4.5, 3.5), (-4.5,10.5), (3.5,3.5) and (3.5,10.5)
The coordinate point is given as:
[tex]\mathbf{(x,y) = (-4\frac12,3\frac12)}[/tex]
Express as decimal
[tex]\mathbf{(x,y) = (-4.5,3.5)}[/tex]
The perimeter is said to be 30 units.
So, we have:
[tex]\mathbf{P = 2(L + W)}[/tex]
This gives
[tex]\mathbf{2(L + W) = 30}[/tex]
Divide through by 2
[tex]\mathbf{L + W = 15}[/tex]
This means that the sum of the dimensions is 15 units.
So, we can assume that:
Length = 8
Width = 7
So, the other coordinates are calculated as follows:
[tex]\mathbf{(x,y) = (-4.5,3.5+7) = (-4.5,10.5)}[/tex]
[tex]\mathbf{(x,y) = (-4.5 + 8,3.5) = (3.5,3.5)}[/tex]
[tex]\mathbf{(x,y) = (-4.5+8,3.5+7) = (3.5,10.5)}[/tex]
So, the possible coordinates are: (-4.5, 3.5), (-4.5,10.5), (3.5,3.5) and (3.5,10.5)
