Answer:
21.2d + 12.4f
Step-by-step explanation:
Given that:
Width of rectangle = (5.5d+9.7f) centimeters
Length of rectangle = (5.1d-3.5f) centimeters
Perimeter of a rectangle : 2 (length + Width)
2 [(5.1d-3.5f) + (5.5d+9.7f)]
2[5.1d - 3.5f + 5.5d + 9.7f]
2[10.6d + 6.2f]
= 21.2d + 12.4f
Hence, the perimeter is :
21.2d + 12.4f)
Answer:
AB=2 ft
ED=4.5 ft
BD=9 ft
m∠ABC=105°
m∠BCD=105°
m∠ADC=75°
Step-by-step explanation:
You need to figure out what m is so first subtract 12 from then sybtract 9 from 9 then you havem by itself. now subtract 4 from 4 then add 4m to 4m and the add 15 to 9 and you should get your answer
