Mathematics for IGCSE & O level - Limits Of Accuracy (Section 1 - No. 4)
A rectangular room measures 5.26m by 3.69m to the nearest centimetre. What is the upper bound of the floor area?
19.408625 m²
19.41 m²
19.44 m²
19.5 m²
Forklaring
The upper bound of the floor area is found by multiplying the upper bounds of the measurements: 5.265 m * 3.695 m = 19.44 m²
