Question

Find the area of a triangle with vertices A(1,4)B(1,7),C(4,7)​

Answer 1

9/2 Sq. units is a Right answer...

Answer 2

• 4.5 units²

Explanation:

Given ΔABC with vertices:

• A(1,4), B(1,7), C(4,7)​

We observe that

AB is vertical segment with length:

• 7 - 4 = 3 units

BC is horizontal segment with length:

• 4 - 1 = 3 units

The area:

• A = 1/2bh
• A = 1/2(3)(3) = 9/2 = 4.5 units²
