How wide are the bars of the cross?

To find the area of the biggest cross that Liza can cut from a square piece of cartolina with a side of 60cm, we need to determine the dimensions of the cross.

A cross consists of two perpendicular lines intersecting at their midpoint. The length of each line will be half the length of the side of the square.

Therefore, the length of the cross's lines will be 60cm/2 = 30cm.

To find the area of the cross, we need to calculate the area of the rectangle formed by the two perpendicular lines.

Since each line has a length of 30cm, the width of the rectangle will also be 30cm. The length will be twice the length of one line, which is 2 * 30cm = 60cm.

Now, we can calculate the area of the rectangle by multiplying its length by its width:

Area = Length * Width
= 60cm * 30cm
= 1800cm².

Thus, the area of the biggest cross that Liza can cut from the square piece of cartolina is 1800cm².
