If the radius of a circle is tripled, the area becomes

Area of the shaded portion is

In the given figure,$\mathit{ }ABCE$ is a parallelogram. $P$ is the midpoint of $AD$ and $AD\perp EC$. If  $AD=20 \mathrm{cm}$ and  $EC=18 \mathrm{cm}$, then find the area of the given figure.

A field is $225 \mathrm{m}$  long and $175 \mathrm{m}$ wide. It has two roads in its centre of uniform width of $5 \mathrm{m}$, one parallel to its length and the other parallel to its breadth. Find the cost of levelling the roads at $₹3$ per ${\mathrm{m}}^2$.

People of a village take good care of plants, trees and animals. They marked some land for their pets (cow and ox) and plants. Find the ratio of the areas kept for animals and plants to the total area of the village.

A rectangular field is $112 \mathrm{m}$ long and $100 \mathrm{m}$ wide. Two roads, each $3 \mathrm{m}$ wide are to be constructed at the centre of the field; one is parallel to the length of the field and the other is parallel to the breadth of the field.

(i) Area of the part of the field, not covered by the roads.

(ii) Cost of constructing the road at $₹17$ per ${\mathrm{m}}^2$.

Which of the following statements is true?

 Statement$‐1$: A saree  $5.5 \mathrm{m}$ and $1.25 \mathrm{m}$ wide has a zari border $2.5 \mathrm{cm}$ broad along its length on either side. Along the width, on one edge the border was $5 \mathrm{cm}$ wide and on the other side the zari was $25 \mathrm{cm}$ wide. The area of the zari is $5855 {\mathrm{cm}}^2$.

Statement$‐2$: The moon is about $384000 \mathrm{km}$ from earth and its path around the earth is nearly circular. The length of path described by moon in one complete revolution will be $2,411,520 \mathrm{km}$. $(\mathrm{\pi }=3.14)$
