The figure can be separate into a triangle, a rectangle and a trapezium.
Triangle:
Area = 1/2 x base x height
Area = 1/2 x 16 x (25 - 4) = 168 units²
Rectangle:
Area = length x Width
Area = 16 x 4 = 64 units²
Trapezium:
Area = 1/2 (a + b) x h
Area = 1/2 (25 + 15) (10) = 200 units²
Total Area = 200 + 64 + 168 = 432 units²
Answer: 432 units²

The number of boxes of tiles is 6. The correct option is A.
The space occupied by any two-dimensional figure in a plane is called the area. The space occupied by the circle in a two-dimensional plane is called as the area of the circle.
Given that a circular playground for a daycare centre is to be covered with square tiles that are 9 inches on each side. The circle has a diameter of 12 ft. The tiles are packaged in boxes of 25 tiles.
The area of the circle is,
A = π x r²
A = π x 6²
A = 113 square ft
The area in square inches is,
A = 113 x 12 = 1356 square inches
The number of tiles will be,
Number = 1356 / 9
Number = 150
The number of boxes,
N = 150 / 25
N = 6 boxes
Therefore, the number of boxes will be 6.

What is the shape of the following cross section????
The shape of the triangle is the cross-section part of the given figure. Thus, option A is correct.
The cross-section part of the given figure could be the shape fro the inscribed figure.
Here we can see that the three-dimensional figure inscribed in the square is a cone.
The right circular cone is the cone in which the line joining peak of the cone to the center of the base of the circle is perpendicular to the surface of its base.
But for the plane of the square, the triangle is the cross-section part of the given figure.
