Rachel made a mosaic from different color rectangular tiles. three tiles measured 312 inches by 3 inches. six measured 4 inches by 314 inches. what is the area of the whole mosaic in square inches?

First, find out what the measurements are. in order to do so, multiply the sides by each other since l*w=area.
•(312*3)=936 and (314*4)=1256
•this means that three tiles each equals 936, while six tiles each equals 1256

next, use multiplication to find out the total area by multiplying 3 for the number of tiles there are for the ones that measure 936, and multiplying 4 by 1256.
• (936*3)=2808, (1256*4)=5024
to find the total area, add the two numbers
• 2808+5024= 7832
The area of the whole mosaic is 7832 square inches.

Ithink the answer is c just trying to others
