rectangle?
(1) 576 sq. cm
(2) 484 sq. cm

(4) 169 sq. cm
​

Answer 1

Answer:

(2) 484 sq. cm

Step-by-step explanation:

Hi there,

The question requires us to find the length of the rectangle firstly.

We can do this by using formula

Perimeter=2(l+b)

=>34=2(l+6)

=>Length of rectangle=11 cm

The side of the new square is therefore 22 cm. The area of this square is thus (a^2)=22*22=484 sq. cm.

Hope it helps:)
