Question

The side lengths of a square (L) are increasing at a constant rate of 2 cm/min. If the area of a square is A.

Then dA/dL is equal to?

Answer 1

A= L^2 ===> dA/dL= 2L *dL/dt === > 2L *2 = 4L

Answer 2

the answer is 2L

Answer 3

oh yeah its right sorry lol i didn't see your s da/dl

Answer 4

ok , great

Answer 5

it depends on the law of area

Answer 6

so the area of a square is L x B so thats why its L^2

Answer 7

since B = L in the square, it's better to write the area in this form A=L*L =L^2

Answer 8

i see thank you very much :)

Answer 9

yoy are welcome
