Answer:
Combine Like terms and do the Equation normally
Step-by-step explanation:
Area = l x w
Area =9 x 4.25
A = 48.25
A≈ 48 in²
20.25-9(1/2)+11
=20.25-4.5+11
=26.75
We can say L as length and W as the width
L= 3w + 8
The formula for perimeter is 2L + 2W = P. We can substitute L in as "3w+8" to make the equation...
2(3w+8)+2w=88 Now, we can simplify by distributing the 2 to each term
6w+16+2w=88
8w+16=88 Then subtract 16 from each side..
8w=72
w=9
So the width is 9, so we can substitue that into the previous equation, L = 3w+8.
L=3(9)+8
L=27+8
L=35, W=9
