The area of the triangle is 3.5 square units
How to determine the area of the triangle?
The coordinates of the triangle are given as:
J = (-3, 4)
K = (4, 4)
L = (3, -3)
The area of the triangle is calculated as:
A = 0.5 * |x1(y2 - y3) + x2(y1 - y3) + x3(y1 - y2)|
So, we have:
A = 0.5 * |-3 * (4 + 3) + 4 * (4 + 3) + 3*(4 - 4)|
Evaluate the sum of products
A = 0.5 * |7|
Remove the absolute bracket
A = 0.5 * 7
Evaluate the product
A = 3.5
Hence, the area of the triangle is 3.5 square units
