a wire is in shape of rectangle its lenghts is 40 cm and breadth is 20 cm if the same wire is rebent to form a square what will be measur of its side
Answers
Answer:
Length of the rectangle = 40 cm
Breadth of the rectangle = 22 cm
Since same length of wire is used to form a rectangle and square, we can say that,
perimeter of square = perimeter of rectangle
4 × Side = 2 (Length + Breadth)
4 × Side = 2 (40 + 22)
4 × Side = 2 × 62
4 × Side = 124
Side = 124/4
Side of square = 31 cm
Area of square = side × side
= 31 cm × 31 cm
= 961 cm2
Area of rectangle = Length × Breadth
= 40 cm × 22 cm
= 880 cm2
Hence, square shape encloses more area.

Answer
A wire is in the shape of a rectangle. ... If the same wire is rebent in the shape of a square, the measure of each side will be 31 cm. Also, square shape encloses more area.
Length of the rectangle = 40 cm
step by step explanation
Breadth of the rectangle = 22 cm
Since same length of wire is used to form a rectangle and square, we can say that,
perimeter of square = perimeter of rectangle
4 × Side = 2 (Length + Breadth)
4 × Side = 2 (40 + 22)
4 × Side = 2 × 62
4 × Side = 124
Side = 124/4
Side of square = 31 cm
Area of square = side × side
= 31 cm × 31 cm
= 961 cm2
Area of rectangle = Length × Breadth
= 40 cm × 22 cm
= 880 cm2
