Answer:
- lower boundary: 788 cm
- upper boundary: 792 cm
Explanation:
You want the boundary values on the perimeter of a garden measured at 252 by 143 cm.
Perimeter
Each measurement is given to the nearest cm, so may have an error of ±0.5 cm. The perimeter is the sum of the measurements of the sides, so is ...
P = 2(L +W)
P = 2((252 ±0.5) +(143 ±0.5)) = 2(395 ±1.0) = 790 ±2.0
The boundary values on the perimeter length are 788 cm and 792 cm.
