What does the b and h stand for in the area formula of a parallelogram?
b = base
h = height
What is perimeter of a rectangle with length 8 cm and width 4 cm?
A = 8 cm + 8 cm + 4 cm + 4 cm
A = 24 cm
P = 6 ft + 4 ft + 9 ft
P = 19 ftFind the area of a trapezoid with b1 = 5 cm, b2 = 7 cm and h = 9 cm
A = (5 cm + 7 cm)9 cm/ 2
A = 54 cm2
C = 31.4 cm

320 m2
w = width
Find the area of a triangle if it has a base of 6 m, a height of 8 m.
A = (6 m * 8 m)/2
A = 24 m2
A = 3.14 * 92
A = 254.34 cm2
Find the area of a parallelogram if it has a base of 9.2 in, a height of 10.5 in.
100.28 in2
A = 11 ft * 9 ft
A = 99 ft2
A = (7 ft * 10 ft)/2
A = 35 ft2
Find the area of the trapezoid with b1 = 15 in, b2 = 20 in, h = 12 in.
A = (15 in + 20 in)12/2
A = 210 in2
A = 3.14 * 72
A = 153.86 cm2
