A rectangle is cut in half to create two squares that each have an area of 25. What is the perimeter of the original rectangle?
30
20
25
50
Detailed Explanation
The correct answer is (C). The formula to find the area of a square is Side × Side. If each square has an area of 25, then each side of the square must be 5 (because 5 × 5 = 25). So the dimensions of the rectangle are 5 × 10. The perimeter is the sum of all the sides, and is therefore 5 + 10 + 5 + 10 = 30.
