The answer for j is 16 and the answer for k is 21
D = √(x2 - x1)^2 + (y2 - y1)^2) =
= √(6 + 1)^2 + (-2 - 4)^2) =
= √ (7^2 + 6^2) =
= √(49 + 36) =
= √85
Answer:
lateral area = side area = (10 x 6 x 2) + (14 x 10 x 2) = 400 in²
total surface area = lateral area + top & bottom area = 400 + (14 x 6 x 2) = 568 in²
Option D is the correct one.
