A = b * h
420 = 35h
420/35 = h
420 = 35h
420/35 = h

Question 18 (2 points)
Find the area of the regular polygon. Round your answer to the nearest tenth.
a 673.3 inches squared
b 483.2 inches squared
c 336.6 inches squared
d 966.4 inches squared
the 10 is alone the outside of one of the sides and there is a dot in center and a dashed line that goes to one segmement. is is 13.07
10 = 2* 13.07 sin (180/n)
sin (180/n) = .382555
180/n = 22.5
n = 8 sides
360/8 = 45 = top angle of each isoceles triangle
half of that has hpotenuse of 13.07 and base of 5
area of each of those 16 triangles = (1/2) (5)(13.07 cos 22.5) = 30.2
16*30.2 = 483
Area = base * height
From the given information, we know that the area of the parallelogram is 420 cm² and the height is 35 cm.
So, we can substitute these values into the formula:
420 cm² = base * 35 cm
To find the value of the base, we need to isolate it on one side of the equation. To do this, we can divide both sides of the equation by 35 cm:
420 cm² / 35 cm = base
Simplifying this expression, we have:
12 cm = base
Therefore, the corresponding base of the parallelogram is 12 cm.
The label for the answer would be: base = 12 cm.
