Answer:
a) 10x² - 3x - 18
b) 14x + 6
Step-by-step explanation:
<u>Given:</u>
length = 5x + 6
width = 2x - 3
Tables usually have rectangular shape.
a) Area of the table
<u>Area of a rectangle</u>
A = length × width
Insert values into formula.
A = length × width
A = (5x + 6) × (2x - 3)
A = 10x² - 15x + 12x - 18
A = 10x² - 3x - 18
b) Perimeter of the table
<u>Perimeter of a rectangle</u>
P = 2 × length + 2 × width
P = 2 × length + 2 × width
P = 2(5x + 6) + 2(2x - 3)
P = 10x + 12 + 4x - 6
P = 14x + 6
