Length(l)= 2w
width(w)= w
Perimeter(P)= 2w+2l= 72 (simplify expression: divide each side by 2 )
P= w+l= 36 (plug in "2w" for "l")
P= w+(2w)= 36
P= 3w= 36 (divide each side by 3 to find the width)
w= 12 units
find length:
l=2w
l= 2(12)
l= 24 units
Answer:
The length of this rectangle is 24 units and the width is 12 units.
2) $3.85
5)125
7)175cm
10) 10 000cm2
11) $4.10
12)4
13)575mL
Answer:
-6g + 36 = 12
36 = 12 + 6g
24 = 6g
4 = g
g = 4
