The perimeter of a square with a side of 8 cm is equal to the perimeter of a rectangle with a side of 10 cm. What is the area of a rectangle?

The first step is to calculate the perimeter of the square:
1) 4 * 8 cm = 32 cm perimeter of the square.
Now let’s calculate the length of the second side of the rectangle. Let’s take it for x cm:
2 * (10 + x) = 32.
10 + x = 32: 2.
10 + x = 16.
x = 16-10.
x = 6.
Now let’s calculate the area of a rectangle using the formula the product of its length and width:
2) 10 cm * 6 cm = 60 cm2 area of a rectangle.
Answer: the area of the rectangle is 60 cm2.
