The length of two semicircles of diameter 10 is the circumference of a circle of that diameter:
C = πd = 10π ≈ 31.4
The perimeter includes that length plus the lengths of two straight sides that are 15 units each.
P = 31.4 + 2×15
P = 61.4 . . . . units

<h2>Greetings!</h2><h3>When multiplying two roots together, you can rearrange the equation so that the roots are next to each other and so are the whole numbers:</h3>
2 x 3 x 
x 
<h3>This means that 2 x 3 is simple, = 6,</h3><h3>But when multiplying
you simply multply the two numbers and put them in a square root:</h3>
= 
<h3>But this can be square rooted to 6, which then means that the equation is now:</h3>
2 x 3 x 6 = 36
<h3>So the simplified form is 36.</h3>
