Step-by-step explanation:
The question says the original mosaic is surrounded by a 3 inch by 5 inch frame. The length has 5 squares & the width has 3 squares, so that means each square is an inch long.
1. Perimeter is adding up how long all the sides are. So for the original you add 3 + 5 + 3 + 5 = 16 inches
2. Area is length x width, so we multiply 3 x 5 = 15 inches squared
3. Since each square is an inch, to find the length we add up all the squares & we get 10. Then we do the same for the width & get 6. To figure perimeter, we add up all the sides 10 + 6 + 10 + 6 = 32 inches
4. Area is length x width, so 10 x 6 = 60 inches squared
5. For the original we needed 16 inches of steel. For the larger one, we needed 32 inches. 32 inches is 2x bigger than 16.
6. For the original we had an area of 15 inches squared. For the larger one we had 60 inches squared. 60 is 4x bigger than 15.
