Answer 1

A rectangular yard is 22 ft by 19 ft. The yard is covered with grass except for a square flower garden 10.5 ft long. How much grass is in the yard? The area covered by grass is (Type a whole number or a decimal.) ​

we have that

The area covered by grass is equal to the area of a rectangular yard minus the area of the square flower garden

so

A=(22)(19)-(10.5)^2

A=307.75 ft2
