Answer:
(7m + 10) yards of cloth was used
Step-by-step explanation:
This is a multiplication problem. Firstly, we are told that she sew m shirts and she used 2 yards of cloth for each of the shirts. The total amount of materials used here is m * 2 = 2m yards
She also sew another (m + 2) Shirts using 5 yards of materials for each of the shirts. The total amount of materials used is thus 5(m + 2) which equals (5m + 10) yards
The total amount of cloth used altogether is thus 2m + (5m + 10) = (7m + 10) yards of cloth
