Question 4.
\nThe area of a rectangular garden 50 m long is 300 sq m. Find the width of the garden.
\nAnswer:
\nLength of rectangle
\n= 50 m and Area of rectangle = 300 m2 <\/sup>Since, Area of rectangle
\n= length \u00d7 breadth
\nTherefore, breadth
\n\\(\\frac{\\text { Area of rectangle }}{\\text { Length }}\\) = \\(\\frac{300}{50}\\) = 6m
\nThus, the breadth of the garden is 6 m.<\/p>\n

Question 5.
\nWhat is the cost of tiling a rectangular plot of land 500 m long and 200 m wide at the rate of \u20b9 8 per hundred sq m?
\nAnswer:
\nLength of land
\n= 500 m and Breadth of land = 200 m
\nArea of land = length \u00d7 breadth
\n= 500 m \u00d7 200 m = 1,00,000 m2<\/sup>
\nCost of tilling 100 sq. m of land = 8
\n\u2234 Cost of tilling 1,00,000 sq. m of land
\n\\(\\frac{8 \\times 100000}{100}\\) = 8000<\/p>\n

Question 6.
\nA table-top measures 2 m by 1 m 50 cm. What is its area in square metres?
\nAnswer:
\nLength of table = 2 m
\nBreadth of table = 1 m 50 cm = 1.50 m
\nArea of table = length \u00d7 breadth
\n= 2 m \u00d7 1.50 m = 3 m2<\/sup><\/p>\n

Question 7.
\nA room is 4 m long and 3 m 50 cm wide. How many square metres of carpet is needed to cover the floor of the room?
\nAnswer:
\nLength of room = 4 m
\nBreadth of room = 3 m 50 cm = 3.50 m
\nArea of carpet = length \u00d7 breadth
\n= 4 \u00d7 3.50= 14 m2<\/sup><\/p>\n

Question 8.
\nA floor is 5 m long and 4 m wide. A square carpet of sides 3 m is laid on the floor. Find the area of the floor that is not carpeted.
\nAnswer:
\nLength of floor
\n= 5 m and breadth of floor = 4 m
\nArea of floor = length \u00d7 breadth
\n= 5m \u00d7 4m = 20m2<\/sup>
\nNow, Side of square carpet = 3 m
\nArea of square carpet = side \u00d7 side
\n= 3 \u00d7 3 = 9 m2<\/sup>
\nArea of floor that is not carpeted = 20m2<\/sup> – 9m2<\/sup> = 11m2<\/sup><\/p>\n

Question 9.
\nFive square flower beds each of sides 1 m are dug on a piece of land 5 m long and 4 m wide. What is the area of the remaining part of the land?
\nAnswer:
\nSide of square bed = 1 m
\nArea of square bed = side \u00d7 side
\n= 1m \u00d7 1m = 1m2<\/sup>
\n\u2234 Area of 5 square beds = 1 \u00d7 5 = 5 m2<\/sup>
\nNow, Length of land = 5 m
\nBreadth of land = 4 m
\n\u2234 Area of land = length \u00d7 breadth
\n= 5 m \u00d7 4 m = 20 m2<\/sup>
\nArea of remaining part
\n= Area of land – Area of 5 flower beds = 20 m2<\/sup> – 5 m2<\/sup> = 15 m2<\/sup><\/p>\n
