Here's the solution,
there's a rectangle with sides 4x and 2x
So, area of rectangle :
=》4x × 2x
=》8x²
now, let's divide the kite into two equal triangles with base = 4x
and height = x
area of each triangle :
=》
=》
=》
=》
now, area of each triangle = 2x²
and there are two triangles so,
Area of the kite will be :
=》2 × 2x²
=》4x²
Area of shaded region =
=》Area of rectangle - Area of kite
=》8x² - 4x² = 4x²
hence, correct option is B.
The answer is 153+(-152)= 1
Answer:
A prism whose cross-section is a 60-sided polygon has 120 vertices.
Step-by-step explanation:
A polygon has the same quantity of sides and vertices, as a prism has two poligonal faces, the number of vertices is double the quantity of vertices of the 60-sided polygon. That is:
A prism whose cross-section is a 60-sided polygon has 120 vertices.
Volume = length * width * height Plugging in given values:-
1664 = 16 * w * 8
w 1664 / 16*8 = 13
Width is 13 cms Answer
120 x 0.20= 24. here you go
