Question

Farmer John needs to build a new watering trough for his horses. He has laid out a diagram on grid paper so he knows how much material to buy. each unit mark represents 1 foot, what is the total square footage of material he needs to buy

Answer 1

what is the total square footage of material he needs to buy​ ?

So, we need to find the area of the shown figure :

There are 3 rectangles in the middle, and two squares on the sides

The area of one rectangle = 2 * 1 = 2 square foot

The area of one square = 1 * 1 = 1 square foot

So, total area = 3 * 2 + 2 * 1 = 6 + 2 = 8 square foot

So, the answer is : total square footage = 8
