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.
