PQRS is a square piece of land of side 56 m. Two semicircular grass covered lawns are made on two of its opposite sides as shown in the figure. Calculate the area of the uncovered portion.

In the adjoining figure, ABCD is a square of side 10 cm and two semicircles with side of the square as diameter. A quarter circle is also seen in figure with side of square as radius. Find the area of the square region excluding the shaded part (deepak). (Take pi = 3.14 )

There are two circular flower beds on two sides of a square lawn ABCD of side 56 m. If the centre of each circular flower bed is the point of intersection of the diagonals of the square lawn, find the sum of the areas of the lawn and the flower beds.

In Figure, two circular flower beds have been shown on two sides of a square lawn ABCD of side 56m. If the centre of each circular flower bed is the point of intersection of the diagonals of the square lawn, find the sum of the areas of the lawns and the flower beds.

In the following figure, PQRS is square lawn with side PQ = 42 metres. Two circular flower beds are there on the sides PS and QR with centre at O, the intersections of its diagonals. Find the total area of the two flower beds (shaded parts).

It is proposed to add to a square lawn measuring 58cm on a side, two circalar ends. The centre of each circle is the point of intersection of the diagonals of the square. Find the area of the whole lawn.

Four point masses are placed at the corners of a square of side 2 m as shown in the figure. Find the centre of mass of the system w.r.t. the centre of square.

The given figure shows a square ABCD of side 20 cm. Semicircle are drawn with each side of the square as diameter. Find the area of the shaded portion. (Use pi = 3.14 )
