<u>Linear approximation formula</u>
Given function:
Use the chain rule to differentiate the function.
Differentiate the two parts separately:
Put everything back into the chain rule formula:
.
The <u>linear approximation</u> at a = 8 is:
Finally, substitute x = 7.8 into the <u>linear approximation equation</u>:

Answer:
A = 2.42 sq. meters
Step-by-step explanation:
13 feet = 13 × 0.305 = 3.965 meter
2 feet = 2 × 0.305 = 0.61 meter
A = lw
A = (3.965) × (0.61)
A = 2.41865 sq. meters
A = 2.42 sq. meters
