S(20)=
5*20-2=100-2=98
Say width equals x.
Length = 3x - 4
Solve for x: 72 = 2(3x - 4) + 2x
72=6x-8+2x
80=8x
X=10
So width = 10
Length= 3(10) - 4 = 26
Answer:
x = 8
Step-by-step explanation:
10x - 2 (x + 6) = 52
Let X become 8
10 (8) - 2 (8 + 6) = 52
80 - 2 (14) = 52
80 - 28 = 52
52=52
7 x 5 = 35
1/2(7) x 2
3.5 x 2
7
35 + 7 = 42 Units squared
