Area of Rectangle and Square

The perimeter of a rectangular field is $120 m$. If its length is $35 m$, find its width. Also, determine the cost of levelling the ground at the rate of $₹35 per m^2$.

Find the area of the following figure:

Determine the perimeter of the following figure:

If a floor of length $18 \mathrm{m} 12 \mathrm{cm}$ and breadth $15 \mathrm{m} 60 \mathrm{cm}$ is to be covered with six carpets with each of sides $2 \mathrm{m} 20 \mathrm{cm}$, then determine the area of the remaining part of the floor.

The length and breadth of the wall of a room is $8 \mathrm{m} \mathrm{and} 600 \mathrm{cm}$ respectively. A poster of a square shape of sides $5 \mathrm{dm}$ is pasted on the wall. Determine the area of the part of the wall which is covered by the poster.

A painting is 80 cm wide and 1.6 m long. The ratio of its length to its perimeter in the simplest form is:

If the sides of a square are doubled, then its area:

Find the area of rectangle which has length 7 cm and breadth 4 cm.

 What is the area of a square, if the perimeter of a square is $20 cm$?

If the area of a square plot is $144 sq m$, then its perimeter will be $58 m$.

To determine the cost of tiling a room, we find its area.

 If the side of a square becomes half, then its area becomes one-fourth.

 If the total cost of flooring a hall at the rate of $₹58 per sq m$ is $₹17,400$ and the length of the hall is $25 m$, determine its perimeter.

The side of a square is $6 cm$. A rectangle of side $8 cm$ has the same perimeter as that of the square. Then, calculate area of rectangle and area of square.

 A room is in the shape of a square of side $4 m$. Calculate the area of the floor. What is the cost of flooring at the rate of $₹2.4 per square cm$?

There are two plots, one in a rectangular shape and another in square shape. Both the plots have same area. If a side of square plot is $2 m 10 cm$ and the length of rectangular plot is $12 m 60 cm$, then find the breadth of the rectangular plot.

Naveen was planning to buy a piece of land. So he consulted a contractor, who shared with him details of two places with structures as follows:

Find cost of levelling the ground of both the figures a and b at the rate of $₹14.50 per square metre$.

Naveen was planning to buy a piece of land. So he consulted a contractor, who shared with him details of two places with structures as follows:

Find area of both the figures.

How many square tiles of side $9 cm$ will be needed to fit in a square floor of side $720 cm$. Find the cost of tiling at the rate of $₹5$ per tile.

How many tiles of length and breadth $12 cm$ and $8 cm$, respectively, are needed to cover a rectangular region of length and breadth $5 m 20 cm$ and $1 m 40 cm$, respectively?
