You need to find the area of the rectangle first, doing 15*20=300.
Then, divide it by 2, because you need to find the area of the triangle.
You have 150. Finally, multiply by 12. There you have it!
Please put brainliest if you can.
so basically your going to square 15 and 20 then add them together and find the square root of the answer you got so 15 squared is 225 and 20 squared is 400 add them together which is 625 then find the square root of it which is 25
