Answer:
Step 2: 47
Step 3: 84
Step 4: 114
Step-by-step explanation:
Step 2: The width is 21, and the length is 36.
Sum is addition, so it would be 21 + 36.
21 + 36 = 47
Step 3: 47 x 2 = 84
Step 4: Perimeter is all around, whilst area is on the inside. The length is 21, so it is 21 + 21. 21 + 21 is 42. The width is 36, so it is 36 + 36, which is 72. 72 + 42 = 114.
Meters and seconds.
