- GEO a Flat Shape A flat shape 15 a bus dimensional shape that - does not have Space, only a flat plane and 15 - Limited by straight or Curved lines. A Flat shape is a geometric building whose - entire Parts Lie in one plane and are included closed Curve I in the type of closed I two dimens 1005 with simple Therefore, a plane shape I with divides the plane into three mutually Jexclusive sets of points. The First is the 1 set of points in the area Inside the Flat shape, - the Fecond ist the set of points in the Flat shape, and the third is the set of Points - Outside the Flat shape. No. Rectangle Rectangle 15 a two-dimensional Flat thape that has towo pairs of edges of the Fame - length and Paralle!, has four Tight angles - With Facing sider of the same length Regarding the caracteristics and propertres of - rectangular Flat shapes, thes Include the following No Characterretios of a Flat Shape Har Four fides Has Four right angles of equale measure, Namely go degrees. 3. Has two diagonals Har 2 Lines of symmetry Har 2 Axes of rational Symmetry Has rectangular sides that are per pendicular Ho each other Long I wide Shine like the stars. Date: Sevimeter of the rectangle the Perimeter of the Is the sum rectangle that the sur OF siofe that make rep the the lengths of the side Fectangle. Formula For the perimeter of a rectangle: K= K = P+1+P+L =2p+2e 2.(pte) K= perimeternall P= Length e wide/width Perimeter = 2x(p+1) or 2xptaxe Problems example 800 e5cm A refangle has a length of locm and width of 5 cm Calculate the 10 cm Circumference of the rectangle? Know: P=100 e=5cm ansuered: K=2xCPte) = 2x (10cm+5cm) =2x (15) = 30 cm. 50 the Perimetery of the rectangle above 1530cm Date Rofangular Avea The area of a rectangle is the The enfrre Flat bounclad by As sides thir Means that the area of a rectangle is a calculations Of the entire surface of the Flat shape. Formula for the area of a tectangle : L=Pxe =area P= length =width problems example?? scm lo cm A rectangle has a length of locm and width of 5 cm. Calculate the Circumference of the rectengle? Ansurered: know: P=10 cm e: 5cm. Askol = L/are? answered: 2 = pre = 10 cm x 5cm 250 cm. so the areas of al rectanglet above is 50 cm.
