Answer:
P = 180 inches
A = 1800 square inches
Step-by-step explanation:
The perimeter of a rectangle is equal to P = 2b+2h where b=base and h=height. Here the base is 5 feet and the height is 30 inches. They are different measurements and must be in the same. Convert 5 ft into inches by multiplying 5*12 = 60 inches. Substitute b=60 and h=30.
P = 2*60 + 2*30
P = 120 + 60
P = 180 inches
The area of a rectangle is A = b*h. Substitute b=60 and h=30.
A= 60*30
A = 1800 square inches
Total Units = 4+5+9 = 18
so, 1 unit value = 180/18 = 10
Degrees will be : 4(10), 5(10), 9(10) = 40, 50 , 90
The answer for 8 should be c because it is a discount so you get to pay less.
Step-by-step explanation:
solve for surface area
A=6a^2
a=edge
8*.8=6.4
4x+6.4=40
40-6.4=33.6
33.6/4=x
8.4=x
Hope this helps :)
