LOG PROBLEM
What is the length of a rectangle that has a perimeter of 14.6 cm and a width of 3.2 cm?
Solution:
P=2(l+w)
14.6cm = 2(l + 3.2cm)
14.6cm = 2l + 6.4cm
-6.4cm -6.4cm
8.2cm = 2l
/2 /2
4.1cm = l
HOMEWORK
1. P = 12.1 m, w = 2.5 m, l =?
2. P = 7 in, w = 1.5in, l =?
3. P = 125 cm, w = 20 cm, l =?
4. P = 40 m, w = 18 m, l =?
