On a square gameboard that is divided into n rows of n squares each, k of these squares do not lie along the boundary of the gam
Ivan

Answer: 7

Step-by-step explanation:

-if y is the width and the length of area k (see diagram), the difference between n and y is of 2 square sides, one at each side of y.

-therefore, assuming that n is a whole number and that there aren’t half squares, y must be a whole number too because, as previously said, n-y = 2 so y= n -2

-the only perfect square amongst the values for k you listed is 25, so taking n and y as whole numbers the only possible value for k is 25

-therefore y is 5 and n is 7 because n-y = 2 so y + 2 = n

Can someone please help me with this???
Orlov [11]

The green square is 15 ft wide by 15 ft tall.

The area of one green square is 15 x 15 = 225 square feet.

There are 4 sides plus the base : 225 x 5 = 1125 square feet for the green part.

One triangle has a base 15 feet wide and a height of 9 feet.

The area for one triangle is 1/2 x 15 x 9 = 67.5 square feet.

There are 4 triangles: 67.5 x 4 = 270 square feet.

Total: 1125 + 270 = 1,395 square feet.
