Step-by-step explanation:
Lets say w is the width of the flower bed. We can make an equation to find the area.
The length of the of the flower bed is (w+5) and the width is w.
To find the area we need to multiply the length(w+5) by the width(w) and set it equal to 84,
(w+5)(w)=84
w^2 +5w=84
Using the quadratic equation you get the solutions of 7 and -12. Since 7 is positive it is our width. Our length is 7+5 or 12.

Step-by-step explanation:
It is assumed PQS and RQS are similar triangles.
<u>The ratio of corresponding sides is equal:</u>
<u>Substitute side lengths and solve for x:</u>
- 15/(3x - 4) = 21/(5x - 16)
- 15(5x - 16) = 21(3x - 4)
- 5(5x - 16) = 7(3x - 4)
- 25x - 80 = 21x - 28
- 25x - 21x = 80 - 28
- 4x = 52
- x = 52/4
- x = 13
202 because you can round it to 200
