P=2L + 2W
88=2(3w) + 2w
88=6w +2w
88=8w
88/8=8w/8
11=w
If the perimeter is 88 and the width is 11 and the length is 3 times the width then the length is 33 and you plug those numbers into the original formula you get the starting perimeter of 88
P=2L + 2W
P=2(33) + 2(11)
P=66+22
P=88

Shirley estimated the length of a board to be 18 inches. The actual length is 23 inches. To the nearest tenth of a percent, what
artcher [175]

The percent error of Shirley's estimate is 21.74%

<h3>Calculating pecent error</h3>

Given the following parameters

  • Actual length = 23 inches
  • Estimated length = 18in

% error = actual-estimated/actual * 100

% error = 23-18/23 * 100

% error  = 500/23

% error = 21.74%

Hence the percent error of Shirley's estimate is 21.74%
