Answer 1

Answer:

Q9.

1)Measure of each side=31 cm

2)Square encloses more area.

Q11

Cost=6600 Rs

Step-by-step explanation:

Question 9.

When the shape is rectangle its L=40cm and B= 22 cm

given that we can find the perimeter 2(L+B)=2(62)=124cm

assuming there is no wire left after that we can consider the perimeter of the rectangle as the length of the wire.i.e. 124cm

Now to make a square out of it each side should be of length 124/4=31cm.

In that case lets compare are for rectangle and square.

Area of rectangle = L*B=40*22=880 $cm^{2}$

Area of square =$L^{2}$= $31^{2}$= 961

Hence clearly, square has more area than rectangle.

Question 11.

Total perimeter to be covered by fence =20+12+12=20+24=44

rate of fencing= 150 Rs per meter

Cost of fencing = Total perimeter * rate of fencing = 44*150=6600 Rs
