Bell Work Find the area of each figure. 5 in 9 in 13 in 6 in 16 in 22 in 10 in A = (13 + 9) 5 A = 11 5 A = (22) 5 A = 55 in² A = (16 + 22) 10 A = 19 10 A = (38) 10 A = 190 in²

2
Area of Trapezoid 6 in 8 in 2 in A = (b 1 + b 2 ) h 5 in A = (6 + 8) 2 A = (14) 2 A = 7 2 A = 14 in² 5 in Perimeter of Trapezoid P = 5 + 5 + 8 + 6 P = 24 in

4
Area of Parallelogram = Base x Height A = bh Remember: The height is the line segment that is perpendicular to the base and creates a right angle. Formulas Area of Triangle = (Base x Height) A = bh Remember: A triangle is HALF of a parallelogram.

5
Example Find the height of the parallelogram when the area is 252 in² and the base is 36in. 36 in A=bh 252 = 36h h = 7 in 36

6
A treadmill’s belt is in the shape of a parallelogram before the ends are joined to form a loop. The area of the belt is 2052 in². The belt’s width, which is the height of the parallelogram, is 18 inches. Find the length of the belt, which is the base of the parallelogram.

7
b The length of the treadmill’s belt is 114 inches

8
Example Find the base of the triangle when the area is 2400 ft². 50 ft A = bh 2400 = b(50) 2400 = 25b b = 96 ft 25

9
Finding the Base of a Triangle A triangle has a height of 10 centimeters and an area of 35 square centimeters. Find the base of the triangle. Write the formula for area of a triangle. Substitute in values. Simplify. Solve. A = bh 35 = b(10) 35 = 5b b = 7 cm 5 5
