Answer:
A.) w² + 3w in²
B.) 28 in²
Step-by-step explanation:
A.)
Let w = width and l = length.
The area of a rectangle can be written as length · width (base · height). The problem informs us that the length of the rectangle is 3 inches greater than the width. Therefore, l can also be written as w + 3. We can use this to form a polynomial that represents the area of the rectangle.
A(rectangle) = lw = (w + 3) · w = w² + 3w
B.)
Use the polynomial we previously found to find the area.
A(rectangle) = (4)² + 3(4) = 16 + 12 = 28 in²

Answer:
The Area of rectangle ball joint is 1.68 square meters .
Step-by-step explanation:
Given as :
The length of rectangle ball joint = L = 2.1 meters
The width of rectangle ball joint = w = 0.8 meters
Let The Area of rectangle ball joint = A square meters
Now, From The area of rectangle
Area of rectangle = Length of rectangle × width of rectangle
Or, A = L × w
Or, A = 2.1 meters × 0.8 meters
∴ A = 1.68 meters²
So, The Area of rectangle ball joint = 1.68 square meters
Hence The Area of rectangle ball joint is 1.68 square meters . Answer
