Answer: Perimeter = 12 units
Area = length² = 3² = 9 units²
Step-by-step explanation: Draw the points on a Cartesian Plane with linear values on the x- and y-axes and connect the points. Once you’ve connected all the vertices (points), you will realise that the shape is a square. *Each vertex must be given its letter when allocating each point, that way you will see that that C and D are distanced from one another vertically; and that means you should use the y-values of each vertex to find the perimeter and area.*
• The vertical distance from point C and D is 3 units (substract the y-values from one another).
• The HORIZONTAL distance from D to E is 3 units (substract x-values from one another because the vertices are distanced horizontally).
• The vertical distance from E to F is 3 units.
• The horizontal distance from F to C is 3 units.
To calculate perimeter, you add up all the units of each side.
P = 3 + 3 + 3 + 3 = 12 units
After connecting the vertices, you will realise that the polygon is a square, so you use the formula for the area of a square.
A = length² = 3² = 9 units.
