Question

Can someone help me for 25? Thx

Answer 1

For number 25, the student is correct because if you were to add up the perimeters of both the square and rectangle, they each add up to 4x+8

Answer 2

Let's see together

The perimeter is the sum of all sides' length of a shape

so for the rectangle:
x+ x+4 + x + x+4 = 4x + 8

and for the square:
4(x+2) = 4x + 8

So they have the same perimeter

So the student was correct
