Picture D best represents the given situation.
Step-by-step explanation:
Step 1; It is given that Angel assembled twice that of DJ. So if DJ assembled 20 fence stations, Angel would have assembled 40 at the same time. We need to determine what all the given pictures represent to determine which represents the situation.
Step 2;
Picture A - Angel assembled f-number of fence sections while DJ assembled 2f-number of fence sections. So this signifies that DJ assembled twice that of Angel.
Picture B - Angel assembled f-number of fence sections while DJ assembled 4f-number of fence sections. So this signifies that DJ assembled four times that of Angel.
Picture C - Angel assembled 4f-number of fence sections while DJ assembled f-number of fence sections. So this signifies that Angel assembled four times that of DJ.
Picture D - Angel assembled 2f-number of fence sections while DJ assembled f-number of fence sections. So this signifies that Angel assembled twice that of DJ.
So picture D represents the given situation best.
