Plz help will mark you as brainliest (the one who answers the most gets brainliest) u don't have to answer all of them u can just answer 2 or 3

41. s = semiperimeter

s = (a + b + c) /2

s = (120+170+250) /2

s = 270m

d is the correct option.

42. b is the correct option.

43. P = a + b + c

P = 120+170+250

P = 540m

a is the correct option.

44. A = √s((s-a)(s-b)(s-c))

=√270((270-120)(270-170)(270-250))

=9000m²

d is the correct option.

45. length of wire=P - space for gate

= 540 - 3

=537m

b is the correct option.

step-by-step explanation:

two pairs of adjacent sides are of equal length. this implies that one diagonal divides the kite into congruent triangles, and so the angles between the two pairs of equal sides are equal in measure. it also implies that the diagonals are perpendicular.
