velikii [3]

Answer:

#1: 11 cm

#2: 16.5 in

#3: 2.5 feet

Step-by-step explanation:

#1

P=2l+2w Solve for width by substracting 2l on both sides to isolate 2w

P-2l=2w

or

2w=P-2l

Replace.

2w=26-2(2)\\2w=26-4\\2w=22\\w=\frac{22}{2}\\ w=11cm

----------------------------------------------------------------------------

#2

P=2l+2w

P=2(3.5)+2(4.75)\\P =7+9.5\\P=16.5in

----------------------------------------------------------------------------

#3

P=2l+2w

Solve for l

2l=P-2w\\2l=7-2(1)\\2l=7-2\\2l=5\\l=\frac{5}{2}\\ l=2.5feet
