Predict: I predict that this question is going to be about geometry.
Read: A square has a perimeter of 60cm. A rectangle has the shape of two of these squares placed side by side. What is the perimeter of the rectangle?
BIG Question: What is the perimeter of the rectangle
Solution: To find the length of each side, we have to divide 60 by 4 which equals 15. Now if we put to squares side by side, a long side of the recatngle would equal 30cm because we just have to plus 15 to 15. A short side of the rectangle would still equal 15. So 30 plus 15 equals 45. So if we double 45, we get our answer, 90cm.
