Two triangles have the same heights. One triangle has a base length that is twice the base length of the other triangle. Are the

djyliett [7]

Answer:

Yes

Step-by-step explanation:

The formula for area of a triangle is A = (1/2)bh,

For the first triangle we can leave it in general terms, so it's area is

A = (1/2)bh, depending on what b and h are, but it doesn't matter here...

The second triangle has base that is twice the other triangles base. Bases being multiples of each other is the definition of being proportional so the bases are proportional, an the area of the second triangle is

A = (1/2)(2b)h, which simplifies to

A = bh

Comparing the 2 areas, you can see that one has a multiplier of (1/2), so their areas are proportional

A farmer builds a fence to enclose a rectangular pasture.He uses 155 feet of fence. Find the total area of the pasture if it is

ICE Princess25 [194]

The area for the perimeter of a rectangle is:
<em>P = 2l + 2w</em>
In this problem, we are given that P = 155 and l = 45.5. To solve for area, we must find w. To do this, plug in the given info and isolate the w like so:
$155=2(45.5)+2w \\ 155=91+2w \\ (155)-91=(91+2w)-91 \\ 64=2w \\ \frac{64}{2} = \frac{2w}{2} \\ w=32$
Now we know w = 32. Knowing all the necessary info, we can use the area formula, <em>A=lw</em>, to solve for A.
$A=(45.5)(35) \\ A=1,456$

The area is 1,456 sq ft.

Hope this helps!
