a rectangular yard is 25 ft by 19 ft. the yard is covered with grass except for a
9.5-ft square flower garden. how much grass is in the yard?

There is 384.75 sq feet area of grass in the rectangular yard.

Step-by-step explanation:

The dimensions of the rectangular yard = 25 ft x 19 ft

The Area of the yard =  LENGTH x WIDTH

                                  = 25 ft x 19 ft

                                  = 475 sq feet

or, the area of the rectangular yard =  475 sq feet

Now, the side of the square covered with flower garden = 9.5  feet

So, area of the flower garden =  9.5 ft x 9.5 ft = 90.25 sq ft

Now, Area Covered with Grass = Total area of Yard - Area of flower garden

 =  475 sq feet   -  90.25 sq feet

 =   384.75 sq feet

or, the area covered with grass = 384.75 sq feet

Hence, there is 384.75 sq feet area of grass in the rectangular yard.
