Orion · Answer 2

Option A is the correct answer.

Step-by-step explanation:

Area of patio = Length x breadth = 8.75 x 14.8 = 129.5 square feet.

He ordered 135 square feet of bricks, which is greater than required area of brick of 129.5 square feet. So, Dion estimated the amount of brick required by rounding up 129.5 to 135.

Option A is the correct answer.
