I believe the correct answer from the choices listed above is option A. THe correct classification of the polygon in the figure would be a concave hexagon. Counting the number of sides, we have 6 sides making it a hexagon. It is concave since one side is <span>hollowed inward.</span>
Its just pythagorean theorem so you would do this:
a^2+b^2=c^2
30^2+ 13^2= 1069
then u square root the answer (1069)
which would then give you 32.695
and then you round to nearest tenth which is one place after the decimal
32.7 would be your answer for the first one.
Hope that helps!
Width of the rectangle is 16 ft and length of the rectangle is 20 ft
<u>Step-by-step explanation:</u>
Step 1:
Given area of the rectangle = 320 ft². Let the width of the rectangle be x, then the length = x + 4. Use the formula for area of a rectangle = (length × width)
320 = x(x + 4)
320 = x² + 4x
x² + 4x - 320 = 0
x = (-b ±√b² - 4ac)/2a = (-4 ±√16 - 4×1×-320)/2
= (-4±√1296)/2 = (-4 ± 36)/2
= 32/2, -40/2 = 16, -20 (neglecting the negative value)
∴ Width of the rectangle = 16 ft
∴ Length of the rectangle = 16 + 4 = 20ft
Answer:
