The area of the rectangle (S) is determined by the formula:
S = a * b, where a is the length of the rectangle, b is its width.
If the area and length of the rectangle are known, then its width can be determined by the formula:
b = S: a.
Let’s calculate the width of the rectangle, the area of which is S = 42 cm2, and the length is a = 7 cm:
b = 42: 7 = 6 cm.
Answer: The width of the rectangle is 6 cm.
