Answer:
Step 1
The area of the rectangle is calculated by the formula:
area = length x width
Since the dimensions are accurate to 2 s.f. So,
The length of the rectangle is:
600 lies in 595 ≤ x<605
The width of the rectangle is:
120 lies in 115 <x<125
The lower bound of the area is
595 × 115= 68425 cm²
The upper bound of the area is:
605 x 125 75625 cm²
