Question

Help please i need this done i will mark brainlest and it will help me out a lot please

Answer 1

Answer:

Perimeter is (width×height) but in this case it would be base×width & height...

First find the with of the triangle,by measureing the points with the base.

Second to find the base simply look equilateral and the half circle. and see how the lines in between it and the triangle collide. and count the spaces to find the base.

Third measure the height with the best estimate.

And finally, multiply by (h×w) and divide by the base.

After following these steps the answer I have come to is: 45

Step-by-step explanation:

I'm sorry if this is wrong I tried my best ❤️Good luck! and have a great day or night!

Answer 2

Answer:

42,84

Step-by-step explanation:

Remark

Two of the sides are 12 inches. The third side is also 12 but it serves as a diameter of the semicircle.

The circumference of the semi circle is 2*pi*r /2 = pi * r

The total perimeter is pi * r + 2*12

r = d/2

r = 12/2

r = 6

Perimeter = 6*pi + 24 might be you answer.

Perimeter = 42.84

I don't know which answer to use. It all depends how other questions have been answered. Sometimes you take the decimal answer and sometimes you take the answer in terms of pi. I think the latter is what I would try first.
