Answer:
Step-by-step explanation:
<u>The figure consist of:</u>
- 1. A rectangle with sides 10 cm and 17 cm
- 2. A quarter circle
<u>The perimeter is:</u>
- P = 1/4C + 2*10 + 17 + (17 - 8) + 8
- P = 1/4*2*3.14*8 + 54 = 66.56 cm
So to set up the equation we have:
<span><span><span>4M</span><span>4+M</span></span>=<span>127</span></span>
<span>28M=12(4+M)</span>
<span>28M=48+12M</span>
<span>28K−12M=48</span>
<span>(28−12)M=48</span>
<span>16K=48</span>
<span>M=<span>4816</span></span>
<span>M=3</span>
