7. A seed company planted a floral mosaic of a national flag. The perimeter of the
rectangular planting area is 420 feet.
The length of the area is 110 feet longer
than the width.
a. Write a system of equations to relate the
length and width of the planting area.
b. Use the system of equations to
determine the length and width of
the planting area.

w = 160, L = 50

Step-by-step explanation:

Length = 50 feet

Width = 160 feet

First Find the Length

w = l + 110

P=2w+2l

420=2w+2l

420=2(l+110)+2l

420=2l+220+2l

4l=200

l=50

Finding the Width

w=(50)+110

w=160

how to award brainliest:

you must wait until 2 people answer to award brainliest. i'm pretty sure that it should be next to the "" and "comments" buttons.
