This week the think board got our attention that we are learning to find the area and the perimeter of a shape. We had to find the area and the perimeter of a triangle with the sides 15 cm and the base 25 cm, to find the perimeter we have to add everything(15+15+25=55) witch equaled to 55 cm. To find the area we first half the bottom of the triangle witch is 12.5, then we times it by how long the sides are. 12.5x15=187.5. Hope you enjoy and please leave a comment.
