4. The area of a rectangular garden 50 m long is 300 sqm. Find the width of the garden.
5. What is the cost of tiling a rectangular plot of land 500 m long and 200 m wide at the
rate of 58 per hundred sq m.?
6. A table-top measures 2 m by 1 m 50 cm. What is its area in square metres?
7. A 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?

Answer 1

Step-by-step explanation:

Solution:

Length of rectangle = 50 m and Area of rectangle = 300 m.sq

Since, Area of rectangle = length x breadth

Therefore, Breadth = \frac{Area\ of\ rec\tan gle}{Length}

Length

Area of rectangle

= 6m

Thus, the breadth of the garden is 6 m.

Answer 2

Which one has the largest area and which one has the smallest?

_______________________

• The rectangle (c) has largest area, and rectangle (b) has smallest area.

4. The area of a rectangular garden 50 m long is 300 sqm. Find the width of the garden.

_______________________

• Length of rectangle = 50 m and Area of rectangle = 300 m.sq

• Area of rectangle = length x breadth

• Therefore, Breadth =

$\frac{Area\ of\ rectangle}{ \: Length} = 6m$

Thus, the breadth of the garden is 6 m.

5. What is the cost of tiling a rectangular plot of land 500 m long and 200 m wide at rate of 58 per hundred sq m.?

_______________________

• Substitute 'l=500 meters' and 'b=200 meters' in the formula A=lb to find the area of the rectangular plot.
• Hence, the area of the rectangular plot is 105 m2 . Therefore , the total cost of tiling the rectangular plot of dimension
• (500 m x 200 m) is Rs. 8000.

6. A table-top measures 2 m by 1 m 50 cm. What is its area in square metres?

_______________________

• Area of table top
• = L × B = 2 × 1.5 = 3 m².

7. A 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?

_______________________

• Length of the room=4m
• . Width of the room=3m 50cm=3.50m.
• To carpet the room,we have to find the area of the floor. =4×3.50=14 sq.
