Zahra has paper rectangles of different sizes. every rectangle is 5 cm longer than it is wide. is there a proportional relationship between the lengths and widths of these rectangles? explain.

As given Zahra has paper rectangles of different sizes.

Also, Every rectangle is 5 cm is longer than it's breadth.

So, if Length=L, then Breadth= L- 5

Or , if Breadth= B, then Length= B+5

or, if length is x and breadth is y ,then writing in terms of equation

→x=y+5

As you can see,there is not any proportional relationship between length and widths of these rectangles.

No, there is no proportional relationship exist between the lengths and widths of these rectangles.

Step-by-step explanation:

Since, it is given that every rectangle is 5 cm longer than it's width.

⇒ If Width = W, then Length = W + 5

Also, she has a rectangle of different sizes.

Thus, there can't be more relationship exist between Length and Width.

The only relationship between Length and Width is:

W = L + 5

where, W is Width of rectangle.

and, L is Length of rectangle.

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!
