Question

a wire is the shape of rectangle of the length 30 centimetre and breadth is 5 cm it is cut and bent to from another rectangle of breath 10 cm find the length and area of the new rectangle


​

Answer 1

Answer:

According to the question,

Perimeter of square=Perimeter of rectangle

⇒4× side=2(length+breadth)

⇒4×side=2(40+22)

⇒4×side=2×62

⇒ side=

4

2×62

=31cm

Thus, the side of the square is 31cm.

Now, Area of rectangle=length×breadth=40×22=880cm

2

And Area of square=side×side=31×31=961cm

2

Therefore, on comparing, the area of square is greater than that of rectangle.
