Therefore, the answer is option (d).
A customer asked for two extralarge bed sheets. What is the perimeter of each bed sheet?
length of bedsheet= 5m
breadth= 4m
Perimeter of extralarge bed sheet = 5m + 5m + 4m + 4m = 18m.
Therefore, the answer is option (b) 18m.
A customer asked for 2 small bed sheets, 1 large bed sheet and 2 deluxe bed sheets. How much did he/she have to pay?
Price of small bed sheet = Rs.100
Price of deluxe bed sheet = Rs.500

Ramu Kaka is now happy and making more and more profits every day. What area of land he owned now?
Area of land he owned now = 6000 square metre + 5000 square metre = 11000 square metre.
Therefore, the answer is option (d) 11000 square metre.
Area of the given figure = 17 square metre
Therefore, the answer is option (b) 17 square meter.
State true/false for the following statements. A: If a small square of side 1 cm is cut off from the corner, then the boundary will remain the same. B: If a small square of side 1 cm is cut off from the corner then the boundary will get increased. C: If a small square of side 1 cm is cut off the corner then the boundary will get decreased. D: All statements are false.
Boundary of the square = 4cm + 4cm + 4cm + 4cm = 16cm. If a small square of side 1cm is cut off from its corner from the shape would become:
Boundary of new shape = 4cm + 3cm + 1cm + 1cm + 3cm + 4cm = 16cm
Boundary remains same.
So, statement A is true and B, C, D are false.
Therefore, the answer is option TFFF.
Perimeter is expressed in units of length.
Perimeter of the figure = 18cm. Therefore, the answer is option (d) 18cm.
What is the perimeter of a square field whose side is 4 m?
