The perimeter of the unknown length

1 answer:

3 0

Perimeter is equalt to 2l+2w where l is the length and w is the width
or l+l+w+w
so if the perimeter is 14 feet
and the length is 4 feet
14= 4+4+r+r
14= 8+ 2r
6=2r
r=3
the length of one side is 3 feet

Help me as soon as possible PLEASE HELP

Answer:

QRT = 47, TRS = 133

Step-by-step explanation:

Since QRS is a line, QRT + TRS = 180.

$QRT+TRS=180\\3x+5+10x-7=180\\$

Then, solve for x. Combine like terms.

$13x-2=180\\13x=182\\x=14$

Then, plug in 14 for x.

$1. (3*14+5)\\\\QRT = 47\\\\2. (10*14-7)\\\\TRS = 133$
