4. Bell Ringer:
5. Bell Ringer: (answers) b=2 b=4 h=4 h=7 A = (2 x 4) / 2 A=4x7 = 4 sq. un. = 28 sq. un. b = 2.1 b = 21 h = 1.8 h = 12 A = (2.1 x 1.8) / 2 A = 21 x 12 = 1.89 sq. un. = 252 sq. un.
6. There are many other ways to divide trapezoids PQRS. Dividing the trapezoid into rectangles and triangles is called decomposing. After decomposing the trapezoid PQRS into triangles and rectangles, you can find the area of the smaller pieces using the formulas you already know. Finally, add the smaller areas to find the total area of the trapezoid PQRS.
7. To find the side length of a square, find the square Putting it all root of the area. together….
8. Find the area of each composite figure below.
9. Practice: (Answer Key) Triangle: Rectangle: Triangle: b= 8, h= 19 - 13 = 6 A = l x w = 11 x 4 = 44 sq. cm b = 7, h = 8 A = (8 x 6)/2 = 48/2 = 24 sq. in A = (b x h)/2 = (7 x 8)/2 Square: = 56/2 = 28 sq. yd. Rectangle: A = l x w = 5 x 5 = 25 sq. cm A= l x w = 13 x 8 = 104 sq. in Square: Combined Area: A = l x w = 8 x 8 = 64 sq. yd. Combined Area: A = 44 + 25 = 69 sq. cm A= 24 + 104 = 128 sq. in Combined Area: A = 28 + 64= 92 sq. yd.
