PLEASE PLEASE HELP Two rectangular prisms have a side scale factor of 1/4. If the smaller prism has a surface area of 45cm square, what is the surface area of the larger prism? Find the scale factor and area.

Points j and k plotted on the coordinate grid are two vertices of rectangle jklm rectangle jklm has an area of 7 square units point j is located at 2,1 and point k is located at -5,1 each vertex of the rectangle is located at a point that has integer coordinates. what is the perimeter of rectangle jklm? (need answer asap)
