Given:
The lengths of the rectangle have been measured to the nearest tenth of a centimetre 87.3 and 51.8
To find:
the upper bound for the area of the rectangle
Solution:
From given, we have,
The length of the rectangle = l = 87.3 cm
The breadth of the rectangle = b = 51.8 cm
Area of the rectangle = lb = 87.3 × 51.8 = 4522.14 cm²
The upper bound for the area of the rectangle = 4522.14 + 100/2 = 4522.14 + 50 = 4572.14 cm²
