Answer:
Area of new room = 14,616 in².
Step-by-step explanation:
Given : Elly's room measures 78 inches by 96 inches. Sarah's room measures 66 inches by 108 inches.
To find : They want to combine their rooms. How large will the new room be?
.Solution : We have given that
Length of Elly room = 78 inches.
Width of Elly room =96 inches.
Area of Elly room = Length width.
Area of Elly room = 78 96.
Area of Elly room = 7488 in².
Length of Sarah room = 78 inches.
Width of Sarah room =96 inches.
Area of Sarah room = Length width.
Area of Sarah room = 66 108.
Area of Sarah room = 7128 in².
Combine their room = Area of Elly room + Area of Sarah room.
Area of new room = 7488 in² + 7128 in².
Area of new room = 14,616 in².
Therefore, Area of new room = 14,616 in².
