Question

the length of pattys garden is 4 meters greater than 3 times the width. The perimeter of her garden is 72 meters. What are the dimensions of pattys garden?

Answer 1

We start:
\[
l=4+3w\\
2w+2l=72
\]So, we say:
\[
2w+2(4+3w)=72\implies\\
2w+8+6w=72\implies\\
8w+8=72\implies\\
8w=64\implies\\
w=8
\]Since:
\[
l=4+3w\implies\\
l=4+3(8)\implies\\
l=28
\]And we are done.
