Answer:
487.2 in²
Step-by-step explanation:
The area of the semicircle is ...
A = (1/2)πr² . . . . . where r is half the diameter
A = (1/2)π(9 in)² = 40.5π in² ≈ 127.2 in²
The area of the rectangle is ...
A = bh
A = (18 in)(20 in) = 360 in²
Then the total area is ...
total area = semicircle area + rectangle area
= 127.2 in² +360 in² = 487.2 in² . . . . . area of the wood base
The length of side BD is; 13.
<h3>Length measure in a triangle</h3>
From the given diagram;
- It follows that the ratio which holds is;
12 : x = 27 : x + 5
12/x = 27/x+5
27x = 12x +60
- subtract 12x from both sides
15x = 60
x = 4.
On this note, the length of the line BD is;
= BC + CD
= 4 + (4 + 5)
= 4 + (9)
= 13
Therefore, the length of the line BD is 13.
