Answer 2

Answer:

(i) 25cm

(ii) 148cm

Step-by-step explanation:

(i) Breadth of the rectangle

area of the square = area of the rectangle

$a^{2} =$ l × b

$35^{2} =$ 49 × b

1225 = 49 × b

$b=\frac{1225}{49}$

b= 25cm

Therefore the breadth of the rectangle is 25cm.

(ii) perimeter of the rectangle

perimeter of rectangle = $2(l+b)$

= 2(49 + 25)

= 2(74)

= 148cm

Therefore the perimeter of the rectangle is 148cm.
