Hi, I’m Lena and I’ll be here to answer your question with a good-quality answer. If there's something I can improve, let me know! ツ
♡ Let’s look at the main important things that will lead you in the correct path.
♥ <em>a </em>+<em> b</em> usually = <em>c!</em> Unless the book asks you to find a specific variable, you will most likely be looking for <em>c</em>.
♥ <em>A</em> = <em>bh</em>/2! This is the formula for the area of a triangle. You can also read this as A = base * height/2. The good thing about this formula is you don't need a picture. You can write it as <em>a</em> * b<em> </em>or <em>b</em> * <em>a!</em>
<em />
♡ Now, let's solve!
♥ Plug the numbers into the formula: 5*8/2.
♥ Solve! In this case, we do not need c: 40/2 = 20.
Your answer should be 20! Please do not hesitate to ask me any questions.
