An inner city revitalization zone is a rectangle that is twice as long as it is wide. The width of the region is growing at a rate of 34 m per year at a time when the region is 450 m wide. How fast is the area changing at that point in time?

The area is changing at the point of  

Step-by-step explanation:

From the given information:

Let's recall from our previous knowledge that the formula for finding the area of a rectangle = L × w

where;

L = length and w = width of the rectangle

Suppose the Length L is twice the width w

Then L = 2w --- (1)

From The area of a rectangle

A = L  × w

A = 2w  × w

A = 2w²

Taking the above differentiating with respect to time

At the time t

Replacing the values back into equation 2, we get:

hey! so 1 (25) out of 4 (100) is 25 so your answer is 25%. it's like quarters!

after 1 year: 221 deer

step-by-step explanation:

30% of 170 is 51. 170+51=221
