The six sides would be:
2 sides of 14*4=56cm^2, 112 in total
2 sides of 4*6=24cm^2, 48 in total
2sides of 14*6=84cm^2, 168 in total
112+48+168=328cm^2
Answer: 37
Step-by-step explanation:
Well DCB is a right angle, and there is already half which is 53 degrees, subtract 90 by 53 and you will get your answer.
Answer:
The width is 19 units. The length is 21 units.
Step-by-step explanation:
W=width: L=length=W+2; P=perimeter=80
P=2(L+W)
80=2(W+2+W)
40=2W+2
38=2W
19=W answer 1: The width is 19 units.
L=W+2=21 ANSWER 2: The length is 21 units.
CHECK:
P=2(L+W)
80=2(21+19)
80=2(40)
80=80
Answer:
x = 6 sqrt(3)
Step-by-step explanation:
Since this is a right triangle, we can use the Pythagorean theorem
a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse
6^2+ x^2 = 12^2
36 + x^2 = 144
Subtract 36 from each side
x^2 = 144-36
x^2 =108
Take the square root of each side
sqrt(x^2) = sqrt(108)
x = sqrt(36*3)
x = 6 sqrt(3)
