The base, b, of a two-dimensional figure can be any side.
The height, h, is the measure of a perpendicular line
segment from the base to the top of the figure.
Area is the number of square units needed to cover a flat
surface without gaps or overlaps. A square unit is a square
that is 1 unit long and 1 unit wide. To find the area of a figure,
count the number of square units inside the figure. im sure thats right . now
Answer:
84.85cm
Step-by-step explanation:
Let the sides of the square be x
The perimeter of the square = 4x
Get x using the pythagoras theorem
x^2 + x^2 = 30^2
2x^2 = 900
x^2 = 450
x = 21.21cm
Perimeter of the plate = 4(21.21)
Perimeter of the plate = 84.85cm
B)40 because (4)*50/5 is (4)*10
X= -4; f(x)= -15
X= 2; f(x)= 3
X=5; f(x)= 12
