Question

I’m not really sure how to do geometry - can someone please help ?

Answer 1

144 cm squared

Explanation:

For this question, use the formula for area of a triangle (A = 1/2 * base * height)

Plug in the numbers you have, and A = 1/2 * 18 * 16, or 144 cm squared.

Hopefully this helps - let me know if you have any questions!
