1. The rectangle‘s formula is b x w so it would be 8x6 which equals 48.
2. The formula for each Triangle is b x h and you would divide it by two (3 x 8 divided by 2 = 12) but you have 2 triangles that were put together to make it seem like 1 triangle if you can see it. 12 x 2 is 24
3. add your numbers up and you get a total of 72 for number 1. Hoped this helped
