One side of the rectangle is 18cm, and the other is 6cm larger than it. Calculate the perimeter

One side of the rectangle is 18cm, and the other is 6cm larger than it. Calculate the perimeter and area of this rectangle.

We calculate the second side of the rectangle, which, by condition, is 6 cm larger than the adjacent side of the rectangle, equal to 18 cm:

1) 18 + 6 = 24 (cm).

We calculate the perimeter of this rectangle, the sides of which are 18 cm and 24 cm, which is equal to the doubled sum of its two sides:

2) P = 2 (18 + 24) = 2 * 42 = 84 (cm).

Find the area of the same rectangle by the product of its two adjacent sides:

3) S = 18 * 24 = 432 (cm²).

Answer: the perimeter of the rectangle is 84 cm, the area is 432 cm².
