Perimeter and Area

TEKS Referenced:

•3.1(A) - apply mathematics to problems arising in everyday life, society, and the workplace;

•3.6(C) - determine the area of rectangles with whole number side lengths in problems using multiplication related to the number of rows times the number of unit squares in each row;

•3.7(B) - determine the perimeter of a polygon or a missing length when given perimeter and remaining side lengths in problems

•4.1(A) - apply mathematics to problems arising in everyday life, society, and the workplace;

•4.5(C)(D) - use models to determine the formulas for the perimeter of a rectangle (_l_ + _w_ + _l_ + _w_ or 2_l_ + 2_w_), including the special form for perimeter of a square (4_s_) and the area of a rectangle (_l_ x _w_); and solve problems related to perimeter and area of rectangles where dimensions are whole numbers.
