A-length
b-width
perimeter of rectangular floor: 2a+2b=204
<span>The length is two times the width: a=2b
</span>2a + 2b = 204
2*2b + 2b = 204
6b = 204|:6
b = 34
a=2b=2*34=68
a=68->length
b=34->width
Answer:
∠ DBE = 25.5°
Step-by-step explanation:
Given ∠ DBC = 90° and ∠ DBE + ∠ EBC = ∠ DBC, then
∠ DBE = ∠ DBC - ∠ EBC = 90° - 64.5° = 25.5°

Answer:
V =84.78 inches ^2
Step-by-step explanation:
The volume of a cylinder is given by
V= pi *r^2 h
We know h= 12 inches
and r = 1.5 inches
V = pi * (1.5)^2 * 12
V = pi * 2.25*12
V = 27 pi
If we approximate by 3.14
V = 3.14 (27)
V =84.78 inches ^2
