A surveyor is measuring the perimeter of a rectangular piece of land. He measures two adjacent sides to be L=3.56 ± 0.05 m and W = 3.25 ± 0.04 m. These measurements are independent. The value of the perimeter and its absolute uncertainty (respectively) are: Select one: a. 6.810 and 0.090 m b. 13.629 and 0.090 m c. 6.810 and 0.128 m d. 13.620 and 0.128 m e. 13.620 and 0.180 m

Step 1
The formula for the perimeter of a rectangle is P = 2(L + W). Given L = 3.56 ± 0.05 m and W = 3.25 ± 0.04 m, we can plug these values into the formula: P = 2(3.56 + 3.25) = 2(6.81) = 13.62 m Now, we need to find the absolute uncertainty of the perimeter. To do Show more…

A surveyor measures two sides and the included angle of a triangular parcel of land to be $82.04 \mathrm{m}, 75.37 \mathrm{m},$ and $38.38^{\circ} .$ What error is caused in the calculation of the third side by an error of $0.15^{\circ}$ in the angle?
