Who can me with number 12 and 14 ?

300 carrots. You want to find the area of the garden, which you can find by adding the area of the shapes within the garden. You can split the garden into two triangles and a square. The two triangles are equal and form a square with sides of 2 square units, for an area of 4 square units. The square has a side of 4 square units, for an area of 16 square units. You add the 4 square units and the 16 square units to get a total of 20 square units. You would then multiply the 20 square units by the 15 carrots per square unit to get a total of 300 carrots in the garden.
