What is the perimeter of a shape?
Show answer
The total distance around the outside of a shape.
How do you find the perimeter of a shape drawn on a grid?
Show answer
Count the length of each side around the outside of the shape and add them together.
If a square has a perimeter of 24cm, what is the length of one side?
Show answer
6cm. Since a square has 4 equal sides, divide 24 by 4.
If a square has an area of 49cm², what is the length of one side?
Show answer
7cm. The side length is the square root of the area.
What is an equable shape?
Show answer
A shape where the area and perimeter have the same numerical value.
Can two shapes have the same area but different perimeters?
Show answer
Yes. For example, different rectangles with area 12cm² can have different perimeters.
Can two shapes have the same perimeter but different areas?
Show answer
Yes. Different rectangles can have the same perimeter but different areas.
If a square has perimeter 24cm, what is its area?
Show answer
36cm². Each side is 6cm (24÷4), so area is 6×6=36.
If a square has area 49cm², what is its perimeter?
Show answer
28cm. Each side is 7cm (√49), so perimeter is 4×7=28.
