It's ! richard wants to install a paver patio in the shape shown. the dotted line represents a line of symmetry. how many square yards of pavers does richard need to cover the entire patio?   400290180190

The correct option is B. 290 square yards  

Step-by-step explanation:

To find the required area of the figure :

Divide it into two parts , one is triangle and the other is rectangle

Finding the area of triangle :

Base of triangle = 20 yards , Height of the triangle = 20 - 9 = 11 yards

So, Area of the rectangle = 0.5 × Base × Height

⇒ Area of the rectangle = 0.5 × 20 × 11

                                        = 110 square yards

Finding the area of rectangle :

Length of rectangle = 20 yards

Width of rectangle = 9 yards

So, Area of the rectangle = Length × Width

⇒ Area of the rectangle = 20 × 9

                                        = 180 square yards

Therefore, Area needed to be paved to cover the initial patio = Area of rectangle + Area of the triangle

⇒ Area needed to be paved to cover the initial patio = 110 + 180

                                                                                         = 290 square yards

Hence, The correct option is B. 290 square yards
