Find the area of a rectangle if one of its sides is 25 cm, while the other is known to be 7 cm less.

Width – 7 cm less than the length (by condition).
Length – 25 cm (on condition).
We find the width of this rectangle – subtract the number 3 from the length, we get:
25 cm – 7 cm = 18 cm – width.
Area is the product of the length and width of a shape, in this case a rectangle. That is, you need to multiply its length (25 cm) and its width (18 cm).
S = 25 cm * 18 cm = 450 cm².
Answer: 450 cm² – area.
