Alabama Course of Study Standards:
23

Apply area and perimeter formulas for rectangles in realworld and mathematical situations. 
Arkansas Academic Standards:
4.MD.A.3

Apply the area and perimeter formulas for rectangles in real world and mathematical problems
For example: Find the width of a rectangular room given the area of the flooring and the length, by viewing the area formula as a multiplication equation with an unknown factor. 
Arizona  K12 Academic Standards:
4.MD.A.3

Apply the area and perimeter formulas for rectangles in mathematical problems and problems in realworld contexts including problems with unknown side lengths. See Table 2. 
Common Core State Standards:
Math.4.MD.3 or 4.MD.A.3

Apply the area and perimeter formulas for rectangles in real world and
mathematical problems. For example, find the width of a rectangular
room given the area of the flooring and the length, by viewing the area
formula as a multiplication equation with an unknown factor. 
Georgia Standards of Excellence (GSE):
4.GSR.8.3

Solve problems involving area and perimeter of composite rectangles involving whole numbers with known side lengths. 
Massachusetts Curriculum Frameworks:
4.MD.A.3

Apply the area and perimeter formulas for rectangles in realworld and mathematical problems. For example, find the width of a rectangular room given the area of the flooring and the length, by viewing the area formula as a multiplication equation with an unknown factor. (Note: When finding areas of rectangular regions answers will be in square units. For example, the area of a 1 cm x 1 cm rectangular region will be 1 square centimeter (1 cm^{2}, students are not expected to use this notation.) When finding the perimeter of a rectangular region answers will be in linear units. For example, the perimeter of the region is: 1cm + 1cm + 1cm +1cm = 4 cm or 2(1cm) + 2(1cm) = 4 cm). 
North Carolina  Standard Course of Study:
