Question

wire is bent in the shape of rectangle of length 30cm and breadth 10cm. Find the area of rectangle
and if same wire is bent in the shape of a square what will be the measure of a side of square

Answer 1

Answer:

Area of rectangle = length × breadth

= 30 × 10

= 300 cm sq.

side of a square = 30 cm

Answer 2

Answer:

Side of Square = 75 cm

Step-by-step explanation:

As the wire is bent in rectangular form area = length × breadth

Length of rectangle= 30 cm (given)

Breadth of rectangle= 10 cm (given)

Area = l×b = 30 cm × 10 cm = 300 cm²

Here , according to the question the shape of the wire changes but the area remains the same . So , area of Square shape = area of rectangle shape = 300 cm ²

Hence the side of Square = Area / 4

Side of Square= 300/4

Side of Square= 75 cm .
