Answer:
The length is 6
Step-by-step explanation:
6x + 4x+6 + 8x+3 = 63
6x+4x+8x = 63 - 3 - 6
18x = 54
x = 54/18
x = 3
Side AB = 6(3) = 18
Side AC = 4(3)+6 = 18
Side BC = 8(3)+3 = 27
The correct answer is D.
The area is base x height which in this case is 14 x 8 = 112 which is answer choice D.
Hope this helps.
