Problema Solution

Mandy's home has a square kitchen and a rectangular living room. The area of the living room is twice the area of the kitchen. The width of both rooms is the same, but the living room is 10 feet longer than the kitchen. What are the dimensions of the living room?

a * b = 2 *a^2 

=> b = 2a

=> a + 10 = 2a

=> 10 = 2a - a

=> a = 10 , b = 10+10 = 20
