Xiaoming is decorating the house at home, and his mother is going to lay floor tiles on the balcony. This room is 4 meters long and 2 meters wide. Now there are two different types of floor tiles, the specifications and unit price are as follows. 1, 20*20cm, single block area = 0.2 * 0.2 = 0.04m2, balcony area: 8m2, using 200 bricks, with a total price of 200 *10 = 2,000 yuan.

2. 40cm×40cm, single block area = 0.4 * 0.4 = 0.16m2, 50 bricks, total price: 50*25= 1250 yuan.
