Use green's theorem to evaluate integral c
f · dr.
(check the orientation of the curve before applying the theorem.)
f(x, y) = y2 cos(x), x2 + 2y sin(x) c is the triangle from (0, 0) to (3, 18) to (3, 0) to (0, 0)

d) 30 units^2

area of rectangle = l × b

we know,

length = 10 unit

breadth = 3 unit

applying the formula,

= l × b

= 10 × 3

= 30 unit^2

happy to

pls mark as brainliest

answer: h=5.6 i don't really know how to put into words, so i though i would let you do that. i hope i was able to some

step-by-step explanation:

18 = 6(h)+1/2

18 = 6h+1/2

18-1 = 6h/2

17 = 3h

17/3 = h

h = 5.6
