There is a square with sides of 12 cm. Straight lines were drawn through the middle of the sides, breaking the square into 4 identical figures. What is the area of each of the new shapes?

The side of the square is 12 cm;

The square was divided into 4 parts;

Find the area of the new shape.

Decision

First, we find the area of the square.

1) 12 × 12 = 144 cm2;

Then we divide into 4 parts and find out the area of one of the new shapes, which is equal to all the other new shapes.

2) 144 ÷ 4 = 36 cm2.

Answer: 36 cm2.
