The length of a rectangle is 4 in longer than its width.

sertanlavr [38]

Answer:

60 sq in

Step-by-step explanation:

Perimeter = 2l + 2w

If l = w+4

Perimeter = 2(w+4) + 2w

Perimeter = 4w+8

32 = 4w + 8

24 = 4w

6 = w

If w = 6, l = 6+4 = 10

Area = l * w

Area = 10 * 6

Area = 60

Use Green's Theorem to evaluate the line integral along the given positively oriented curve. C yex dx 2ex dy, C is the rectangle

Dennis_Churaev [7]

Answer:

2 ( e^3 + 1 )

Step-by-step explanation:

The path of the attached Rectangle is anti-clockwise

and the Integrand: P( x, y ) dx + q ( x , y ) dy

P( x, y ) = ye^x

q ( x , y ) = 2ex

hence : dq/dx - dp/dy = 2e^x - e^x = e^x

attached below is the remaining solution

using Green's theorem
