Answer:
Approximately 66.4 Meters
Step-by-step explanation:
So we have a rectangle with a width of 18.8 meters and a diagonal with 23.7 meters. To find the perimeter, we need to find the length first. Since a rectangle has four right angles, we can use the Pythagorean Theorem, where the diagonal is the hypotenuse.
![a^2+b^2=c^2](https://tex.z-dn.net/?f=a%5E2%2Bb%5E2%3Dc%5E2)
Plug in 18.8 for either <em>a </em>or <em>b. </em>Plug in the diagonal 23.7 for <em>c. </em>
<em />![(18.8)^2+b^2=23.7^2\\b^2=23.7^2-18.8^2\\b=\sqrt{23.7^2-18.8^2} \\b\approx14.4 \text{ meters}](https://tex.z-dn.net/?f=%2818.8%29%5E2%2Bb%5E2%3D23.7%5E2%5C%5Cb%5E2%3D23.7%5E2-18.8%5E2%5C%5Cb%3D%5Csqrt%7B23.7%5E2-18.8%5E2%7D%20%5C%5Cb%5Capprox14.4%20%5Ctext%7B%20meters%7D)
Therefore, the length is 14.4 meters. Now, find the perimeter:
![P=2l+2w\\P=2(14.4)+2(18.8)\\P=66.4\text{ meters}](https://tex.z-dn.net/?f=P%3D2l%2B2w%5C%5CP%3D2%2814.4%29%2B2%2818.8%29%5C%5CP%3D66.4%5Ctext%7B%20meters%7D)
