A wire is bent to form a square of side 11cm if this wire is re should to form a rectangle of length 16 cm find the breadth of rectangle and area of rectangle |
Answer» Required ANSWER:-A simple logic we have to apply here. We know that the same wire was used to make both the SHAPES. It means the length of the wire is same for both square and rectangle. Hence the perimeter of square = perimeter of rectangle Now, We already have the side of the square, So we can find the perimeter of square because:
Using this, ➛ Perimeter of square = 4 × 11 cm ➛ Perimeter of square = 44 cm The perimeter of rectangle is also 44 cm as per above discussion. And we know that,
Then, ➛ 2(16 cm + Breadth) = 44 cm ➛ 16 cm + Breadth = 22 cm ➛ Breadth = 6 cm And, We have to find the area of the rectangle also.
Using this, ➛ Area = 16 cm × 6 cm ➛ Area = 96 cm² Hence:-
And we are done! :D |
