Answer:

Step-by-step explanation:
The formula for calculate the Area of a rectangle is:

Where "l" is the lenght and "w" is the width.
And the formula for calculate the peimeter of a rectangle is:

Where "l" is the lenght and "w" is the width.
We know that the perimeter of the rectangular baking sheet is 58 inches and its area is 201.25 in². Then:

<u>The steps are:</u>
1. Solve for the "l" from the formula
:

2. Substitute
into the formula
and solve for "w":

Applying the Quadratic formula
, we get:

3. Substitute
into
:

4. Substitute
into
:

Therefore, since the value of the lenght of a rectangle must be greater that the value of the width, we can conclude that the lenght and the width of the rectangular baking sheet are:

Answer:
d=222

Answer:
length is 15.5 and the width is 12.5
Step-by-step explanation:
Length rectangle = 3cm. longer than its width.
Rectangle perimeter = 56 cm.
find its dimensions?
P = 2L +2w
L= w + 3
P= 56
P = 2L +2w
56 = 2(w+3) +2(w)
56 = 2w +6 + 2w
4w= 56 - 6
4w = 50
w = 50/4
w = 12.5
L= 12.5 +3 = 15.5
L= 15.5
Solution:
Length= 15.5 cm
Width = 12.5 cm
i know it looks complex but i hope this helps :)
