How do you find the perimeter and area for complex shapes without a grid?
To find the perimeter and areas of complex shape without a grid you should divide the shape into simple shapes and find the area of each shape alone and then add up the areas all together to get the area of the whole shape. Example: If there is a shape that can be divided into 2 triangles and 1 rectangle then you will find the area of each triangle alone and then the area of the rectangle then add up all the areas together.
What happens if you enlarge a shape by a negative number?
it goes upside down
When you enlarge the sides of a shape to twice their original size the perimeter of the enlargement is times as large as the perimeter of the original shape.?
The perimeter is also twice as large.
What are the five properties of the global grid?

In maths how do you enlarge a shape by the scale factor of 1?
if you multiply all the points by one you get the same points so the shape stays the same.
When you enlarge the sides of a shape to twice their original size the perimeter of the enlargement is times as large as the perimeter of the original shape.?
The perimeter is also twice as large.
What is enlarging and reducing shapes?
Enlarging: When you are enlarging shapes you make it bigger than its normal size but if you were given a grid and your shape or picture was given a gird and if the grids has the same number of squares but the squares in the other gird are bigger, you just need to check the coordinates from your original shape in the grid and draw the other shape in the other gird with the same coordinates. Reducing: You just reduce (make it smaller) the size of the shape but if you were given a grid and your shape or picture was given a gird and if the grids has the same number of squares but the squares in the other gird are smaller, you just need to check the coordinates from your original shape in the grid and draw the other shape in the other gird with the same coordinates. g3
