Question

The area of a square is $49$sq cm. A rectangle has the same perimeter as the square. If the length of the rectangle is $9.3$cm, what is its breadth? Also find which has greater area?

Answer 1

The area of square is $49c{m}^2$

The side of square is $\sqrt{49}=7cm$

The perimeter of square is $4\times 7=28$

$⟹$ The perimeter of rectangle is $28$

The length of rectangle is $9.3cm$

The breadth of rectangle is $2(9.3+b)=289.3+b=14b=14-9.3b=4.7cm$

Area of rectangle is $4.7\times 9.3=43.71c{m}^2$

The square has greates area .
