I'm guessing you mean:

If not, correct me.
So, then the perimeter of a square is just 4*A, which in this case would be:

And that would be your answer:

units²
Answer:
80x2=160 20x3=60 160+60=220
Step-by-step explanation:
Answer:
80°
Step-by-step explanation:
The sum of the angles of any triangle must add up to 180°. If you form a triangle with an angle of 40° and another angle of 60°, the sum of those two angles is 40 + 60 = 100, so the measure of the third angle: 180 - 100 = 80°.
Hey!
First, you would take 349 and subtract 25 from it.(349-25=324) This gets rid of the down payment.
Next, you would divide 324 by 54. (324÷54=6)
It would take him 6 weeks!
Hope this helped! And make sure to check my calculations!

Answer:
(a) x + y = 63 OR 3x = 63
(b) 21
(c) 42
Step-by-step explanation:
Let Vijay's age be x and Ajay's be y.
Ajay is <u>twice</u> as old as Vijay
==> Ajay's age = 2 × Vijay's age
==> <u>y = 2x</u>
<h3>(a)</h3>
<u>Sum</u> of their ages = 63
==> x + y = 63
<em>Substituting</em><em> </em><em>2</em><em>x</em><em> </em><em>for</em><em> </em><em>y</em><em>:</em>
==> x + 2x = 63
==> 3x = 63
<h3>(b)</h3>
<em>Solving the above-obtained equation:</em>
<u>==> x = 21</u>
<h3>(c)</h3>
Ajay's age = 2 times that of Vijay
==> y = 2x
==> y = 2×21
<u>==> y = 42</u>
