This math is so hard

Question

Robert wants to put lights around the front of his house the house is 12 yards long and 7 yards high. How many feet of lights does he need

Answer 1

Hey, Ava

It look's like Robert has a rectangular house and we're putting lights along the roof edge. Or, perhaps the face of the house is a rectangle and we want lights along the ground, roof, and both sides.

If Robert is putting lights along the perimeter of that rectangle, we need to add all four sides.

12 + 7 + 12 + 7 = 38 yards around.

The question is asking how many feet does he need, so multiply your answer by 3 to get from yards to feet.
