Question

Class 6 INDIAN TALL High Order Thinking Section: Two square shaped playgrounds P1 and P2 are side by side. It their an the ratio 4:9 and area of the smaller playground is 144 so an, and the of the other playground
​

Answer 1

Answer:

Main answer is: 72 cm

Step-by-step explanation:

Let area of square P be p and area of square Q be q.

Ratio of areas of squares =  4:9  

⟹p:q=4:9  

⟹144cm2:q=4:9  ————-[ p=144cm2  GIVEN]

⟹144q=49  

⟹q=144×94  

⟹q=36×9  

⟹q=324  

Area of square Q =  324cm2  

Side of square Q =  324cm2−−−−−−√=18cm  

Perimeter of square Q =  (4×18)cm=72cm  

Therefore, perimeter of Q is  72cm
