Area of the word ME = 20 square units

Solution:

Picks' Theorem:

$Area=I+\frac{B}{2}-1$

where <em>I </em>is the interior points and <em>B</em> is the points on the boundary.

Let us first find the area of the letter M:

Number of interior points in M = 0

Number of points in the boundary = 22

Using pick's theorem,

Area of M = 0+\frac{22}{2}-1

Area of M = 10 square units

Now, find the area of the letter E:

Number of interior points in E = 0

Number of points in the boundary = 22

Using pick's theorem,

Area of E = 0+\frac{22}{2}-1

Area of E = 10 square units

Area of the word ME = Area of M + Area of E

                                   = 10 square units + 10 square units

Area of the word ME = 20 square units

To get to work, you drive for 20 minutes at 30 mph, and walk 10 more minutes at 3 mph. What was your average speed?
fiasKO [112]
<span>Note D = r(t)
20min = 1/3 hr and 10min = 1/6 hr

(1/3hr)30mph + (1/6hr)3mph = 10.5 mi, the total distance traveled.

total distance / total time = average speed = 10.5/(1/3 + 1/6) = 10.5/(2/6 + 1/6)
10.5mi/.5hr = 21mph

Hope This Helps </span>
