Answer:
55 cm²
Step-by-step explanation:
side length of square = perimeter/4 = 40/4 = 10 cm.
area of square = side x side = 10 x 10 = 100 cm²
area of triangle #1 = 1/2bh = 1/2(3)(10) = 15
area of triangle #2 = 1/2bh = 1/2(6)(10) = 30
100 - 15 - 30 = 55 cm²
Answer:
3/5
Step-by-step explanation:
I just looked up how to do this since I've never done it before, so if I'm wrong I'm sorry, but from what I found all you have to do is put the opposite(o) over the hypotenuse(h) o/h which would be 9/15 and simplified it would be 3/5, and again if I'm wrong I'm sorry.
I hope this helps, and have a great day!
The greatest common factor would be 4a because it can be multiplied by 8 to be 32a and by 15a^2 to be 60a^3. If this is right could you possibly give me brainliest? Hope this helped.
