Answer:
17 in²
Step-by-step explanation:
area is equal to base multiplied to height by 2
base=3.23 in
height=5.12in
area of one triangle = 5.12 * 3.23/2
= 16.536/2
= 8.2688
these triangles are congruent so area of other triangle is also equal to 8.2688
total area= 2*8.2688
= 16.5376
round off
answer =17 in²
1 mile is equal to 5280 feet.
5/5 - 2/5 = 3/5 of a mile left to walk
3/5m * 5280 ft/1m = (3m*5280ft)/(5*1m) = 15840ft/5 = 3158 feet left to walk to get to work.
Or
5280 feet / 5 = 1056 ft * 2 = 2112 ft walked to get to work
5280 - 2112 = 3168 feet left to walk to get to work.

Answer: 7 inches
Step-by-step explanation:
If x is the first piece, and the second piece is twice as long, then the second piece is 2x.
If the third piece is three times as long as the first piece, x, then the third piece is 3x.
The 42-inch board must be equal to all 3 pieces, so we will set up an equation and solve for x.
42 = x + 2x + 3x
42 = 6x
42 = 6x
7 = x
The first piece is 7 inches long.
