Ron has a square garden with sides of length 8 feet. he plans to enlarge it to a rectangular garden by increasing the length by 2 feet and the width by 1 foot. how many square feet in area will be added to the garden

Here let us find area of square first with side 8 feet.

Area of square = side * side =8*8 =64 feet square(1)

now the dimension of rectangular garden are:

length = 8+2 =10 feet

width =8+1 =9 feet

Area of rectangle =l *w =10*9 =90 square feet (2)

difference = area of rectangle - area of square

plugging values from (1) and (2)

Difference = 90-64 = 26 square feet

So 26 square feet in area will be added to the garden.
