Q1 Rakesh has a rectangular field of length 80 m and breadth 60 m. In it, he wants to make a
garden 10 m long and 4 m broad at one of the corners and at another corner, he wants to
grow flowers in two floor-beds each of size 4 m by 1.5 m. In the remaining part of the field,
he wants to apply manures. Find the cost of applying the manures at the rate of Rs 300 per
area.
Q2. A rectangular field is 30m in length and 22m in width. Two mutually perpendicular roads,
each 2.5 wide , are drawn inside the field so that one road is parallel to the length of the field
and the other road is parallel to its width. Calculate the area of the crossroads.
Q3. From a rectangular sheet of tin, of size 100 cm by 80 cm, are cut four squares of side 10
cm from each corner. Find the area of the remaining sheet.
Q4. A door of length 2 m and breadth 1 m is fitted in a wall. The length of the wall is 4.5 m
and the breadth is 3.6 m (see the given figure). Find the cost of white washing the wall, if the
rate of white washing the wall is Rs 20 per m2.
Q5. A rectangular grassy lawn measuring 40 m by 25 m is to be surrounded externally by a

Q6. One meter wide path is built inside a square park of side 30 m along its sides. The
remaining part of the park is covered by grass. If the total cost of covering by grass is Rs 1176,
find the rate per square meter at which the park is covered by the grass.
Q7. Through a rectangular field of sides 90 m x 60 m, two roads are constructed which are
parallel to the sides and cut each other at right angles through the center of the field. If the
width of the roads is 3 m, find the total area covered by the two roads.
Q8. Each side of a square flower bed is 2 m 80 cm long. It is extended by digging a strip 30 cm
wide all around it. Find the area of the enlarged flower bed and also the increase in the area
of the flower bed.
Q9. There is a rectangular field of size 94 m x 32 m. Three roads each of 2 m width pass
through the field such that two roads are parallel to the breadth of the field and the third is
parallel to the length. Calculate: (i) area of the field covered by the three roads (ii) area of the
field not covered by the roads.
Q10. The length and breadth of a rectangular park are in the ratio 5: 2. A 2.5 m wide path
