The calculation of the perimeter of composite shape #3 in 2 minutes or less
P = 10+11+11+2+2+4+4 +6
P = 50
What is the radius of cirlce B?
What is 7 inches?
Calculate the diameter of the composite blue shape
What is 6?
The name of the perimeter of a slice of bread
What is the crust?
Find the area of the trapezoid in 2 minutes or less
A = 1/2 (b1 + b2) x h
= 1/2 (3 +5) x 12
=1/2 (8) x 12
= 4 x 12
= 48
The calculation of the area of composite shape #4
What is A = 1/2 b + h A = l x w
A = 1/2 (8) + 10 A = 12 x 7
A = 4 + 10 A = 84
A = 14
A = 14 + 84= 98
The formula for the area of a semi-circle
A = π r² /2
Calculate the perimeter of the blue composite shape in 2 minutes
What is 36.84 feet?
The outer edges of two squares and the outer edge or circumference to two semi-circles (which equal one circle) Distance around square parts: 3+3+3+3+3+3=18 Distance around semicircles: C=πd ≈3.14•6 =18.84 So, the perimeter is about 18+18.84=36.84feet.
