given matrix A is 2x3 matrix, matrix C is a 2x1 matrix and A x B = C. what are the demensions of matrix B?

L*W=A 6 x 2 = 12

Step-by-step explanation:

length * weight = area example:you need to measure a full sheet pan and let's say if it is 8 full sheet pan you weighs 23 so you want to multiply 8*23=184 that is your area okay 2*3=6 and 2*1=2 so to figure out the area multiply 6*2=12 so the answer is matrix B just remember length times weight equal areas
