Answer:
Area=77
Step-by-step explanation:
P=36
P=2l+2w
l=w+4
P=2(w+4)+2w
P=2w+8+2w
P=4w+8
36=4w+8
28=4w
w=7
l=7+4
l=11
A=lw
A=77
18 - 6/3
=> 18/1 - 6/3 ... they are unlike fractions becoz different denominators ...so we convert them into like fractions ...(LCM is 3 )
=>18/1 X 3 - 6/3
=> 54/3 - 6/3
=> 48/3
=> 16
Hope it helps !!!

The area of the banner, expressed in simplest form, is: <em>(9 + 3x) ft²</em>
<h3>How to Determine the Area of a Rectangle</h3>
- The area of a rectangle = length × width
The banner given in the image below has a rectangular shape. So, the area of the banner will be determined using the area of a rectangle.
- length = (3 + x) ft
- width = 3 ft
Area of the banner = (3 + x)3
Area = (9 + 3x) ft²
Therefore, the area of the banner, expressed in simplest form, is: <em>(9 + 3x) ft²</em>
