Answer:
Triangle JKL
Explanation:
The formula to find the area of a triangle is :area (A) = (height (H) x base (B)) / 2
You are given the height and base of both triangles, so you just have to plug in the numbers.
Triangles JKL: A = (18 x 18) / 2
A = 162 in^2
Triangel XYZ: A = (16 x 20) / 2
A = 160 in^2
162 is greater than 160, so Triangle JKL has a larger area.
