Answer:
Area of square = 12.48 cm^2
Step-by-step explanation:
Since the square has all sides equal, and when diagonal is made, square form two right angled triangles. Using Pythagoras theorem we can find the length of side of the square.
where c = 5cm and a==b (square has all sides equal)
Putting value of b = a
So, length of side of square = 3.53
Area of square = (3.53)^2
Area of square = 12.48 cm^2.
Answer:
Scale factor: 4:1
Ratio of perimeter: 4:1
Step-by-step explanation:
So basically, there is difference between the ratio of areas and the scale factor.
The area of a shape is equal to the scale factor squared.
We know that the ratio of the 2 areas is 16:1
So, the scale factor must be: ,
Which is basically 4:1
Because the ratio of the scale factor is also equal to the ratio of the perimeter, the ratio of perimeters is also 4:1
