The area of the rectangle is calculated through the equation,
     A = L x W

in which A is the area, L is the length, and W is the width. Substituting the known values to the equation,
   A = (20.0 m)(17.16 m) = 343.2 m²

Since, the least number of significant figures in the multiplier is 3, our answer ought to be in 3 significant figures. The answer to this item is therefore 343 m².

Answer:

Yes, these triangles are congruent

∠E≅∠M

Step-by-step explanation:

Yes, these triangles are similar.

<em>Proof:</em>

Each side in LNM is 1\frac{2}{3} times longer than the sides in GFE

30/18 = 1\frac{2}{3}

25/15=1\frac{2}{3}

20/12 = 1\frac{2}{3}

According CPCTC (corresponding parts of congruent triangles are congruent), angle E is similar to angle M.

Hope this helps :)

Have a good day!

How do you find the x and y intercepts of 5x+4y=-20
irina1246 [14]

To find the y intercept, you cover x and it's coefficient and then divide -20 by 4 to get -5. To find the x intercept, you cover y and it's coefficient and divide 5 by -20 to get -4. So, x = -4 and y= -5
