Answer:
The base of the rectangle is 21 mm.
Step-by-step explanation:
Given that a rectangle's area is 336 mm, and its height is 16 mm, to determine what is the measure of its base, the following calculation must be performed, knowing that the area of a rectangle arises from multiplying its base by its height:
16 x X = 336
X = 336/16
X = 21
Therefore, the base of the rectangle is 21 mm.
30 mi/h= 180 mi/min= 950400 ft/min

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 distance between the two numbers is 23
