Answer:
600ft square
Step-by-step explanation:
Lets multiply all numbers given by 10 beacuse they represent 10 ft
20ft*30ft=600ft square` the area of living room
25ft*20ft=500ft square` the area of bedroom
Its 45 because the triangle has to be 180 and there is a 90 degree angle in the square so 90 divided by two is 45
