Perimeter of a square with 7-cm sides?
The perimeter is 7 cm
What in cm is the perimeter and area of a quadrilateral with vertices at -1 1 and -4 5 and 1 5 and 4 1?
Drawing a sketch shows the quadrilateral to be a parallelogram. Using one side parallel to x-axis as a base → area = length of base × distance between the parallel lines = (4 -- 1) × (5 - 1) = 5 × 4 = 20 square units. For the perimeter you have two parallel sides of length (4 - - 1) = 5 units each And two parallel side of length √((5 - 1)² + (-4 - -1)² = √(4² + 3²) = 5 units each → perimeter = 2 × 5 + 2 × 5 = 20 units Now, if the grid is a centimetre grid, then these are 20 sq cm and 20 cm respectively. If the grid is an inch grid, then 1 in = 2.54 cm → perimeter = 20 × 2.54 cm = 50.8 cm → area = 20 × 2.54² sq cm = 129.032 sq cm For any other grid, you'll need to do the conversion yourself.
How many squares are in a 2 x 2 grid?
4 squares in a 2 by 2 grid 9 squares in a 3 by 3 grid 16 squares in a 4 by 4 grid 25 squares in a 5 by 5 grid 36 squares in a 6 by 6 grid 49 squares in a 7by 7 grid 64 squares in a 8 by 8 grid 81 squares in a 9 by 9 grid 100 squares in a 10 by 10 grid
What is the area of a grid 7×5?
Whats 7x5? 35. That is your answer.
When finding the perimeter of a figure on a grid why do you not count the spaces inside the grid?
That's because "perimeter" means the distance around something - not the spaces inside. If you count squares inside a figure, you are finding the AREA, not the PERIMETER.
