Question

The lab table has a perimeter of 214 inches. The length is 13 inches less than 3 times the width. How many inches long is the table?

Answer 1

Well you know the perimeter would be 2L + 2W (rectangle)

We know the length (L) is 13 less than 3 times the width (W) so that means...

L = 3W - 13

Since we know that...we can substitute that into our equation for L

so

2L + 2W = 214
would become

2(3W - 13) + 2W = 214

Can you solve this from here?

Answer 2

x = 30in, the width. The length is 77in 3%2A30-13



and...

60in+%2B+154in+=214in

Answer 3

L=77?
