Determine the Width
For a rectangle:

Substitute for Area and Length

Multiply both sides by 





-13 (q + 4) = 7q + 16

Step-by-step explanation:
A diagonal makes a rectangle into two right triangles. So if we use the Pythagorean theorem we can find the hypotenuse which is the diagonals.

10^2 + 15^2 = c^2
100+225 = c^2
325 = c^2
18.027 ≈ c
