A rectangle has a length of 9.00 inches and a width of 4.25 inches. What is the area in square inches? Round to the correct significant digits.

Answer 1

38.3 square inches

Explanation:

The product of length and width gives the area of a rectangle:

area = (9.00 in)·(4.25 in) = 38.2500 in²

Each contributor has 3 significant digits, so your rounding rule requires the answer be rounded to 3 significant digits:

area ≈ 38.3 in²
