You first round 289 and get 290 then multiply it by 7

<span>Id reccomend rounding the answer to a easier number, which in this case would show to be 300. Then multiply that by 7, but to make it even easier, take off those Zeros, multiply the 7 by 3, which would be 21, then add the zeros back and you would get a answer close enough to what the question is asking you. </span>

The area of a trapezoid is 69.6 in2 and its altitude is 8.7 in. Find the perimeter of the trapezoid if the sum of its legs is eq
BaLLatris [955]
1. To solve this problem, you must apply the formula for calculate the area of the trapezoid, which is:
 
 A=(B+b)h/2
 
 A is the area of the trapezoid (A=69.6 in²).
 (B+b) is the sum of the bases of the trapezoid.
 h is the height of the trapezoid (h=8.7 in).
 
 2. When you clear the sum of the bases (B+b), you have:
 
 A=(B+b)h/2
 2A=<span>(B+b)h
</span><span> (B+b)=2A/h
</span> (B+b)=2(69.6 in²)/(8.7 in)
 (B+b)=16 in
 
 3. The problem says that <span>the sum of its legs is equal to the sum of its bases, therefore, the perimeter is:
</span> 
 Sum of the legs=Sum of the bases (B+b)=16 in
 
 Perimeter=16 in+16 in
 Perimeter=32 in

Answer:

             x=4\\\\EG=9\\\\ED=18

Step-by-step explanation:

\dfrac{x+5+9}{x+5}=\dfrac{12}{6}\\\\\dfrac{x+14}{x+5}=2\\\\x+14=2(x+5)\\\\x+14=2x+10\\\\14-10=2x-x\\\\x=4\\\\EG=4+5=9\\\\ED=9+9=18
