Elena needs to cut a square piece of wood with an area of 69 square inches.How long should the sides of the square be, rounded to the nearest tenth of an inch

Respuesta :

You need to find the root of 69 since the length and width are multiplied to get the area, therefore it would be 8.3 inches.
8.03 because you need to take the square root of 69. because the area is side times side = Area. x*x=A. A=69. 69=x^2. sqrt(69)=x
