Question

Triangle BCE has vertices B(-1, -2), C(3, -1) and E (3, k) and area of Triangle BCE is 14 units square. Find the possible values of k.

Answer 1

Answer:k = 7

Step-by-step explanation:

Area = 14 square units

1/2 × [-1(-1-3) + 3(k+2) + 3(-2+1)] = 14

(-1×-4) + 3k +6 -6 +3 =14 ×2

4+3k+3 = 28

3k = 28 - 4 - 3

k = 21/3

k = 7
