The area of the rectangular field is 468cm².
Step-by-step explanation:
If, length is 18cm; width is unknown( let x represent width). Then,
<u>Perimeter of a rectangle</u>= Length + Width+ Length + Width
88= 18 + x + 18 + x
88= 36 + 2x
88-36 =2x
52= 2x
52/2=2x/2
26=x
•x=26cm
<em>The</em><em> </em><em>width</em><em> </em><em>of</em><em> </em><em>the</em><em> </em><em>rectangle</em><em> </em><em>is</em><em> </em><em>2</em><em>6</em><em>c</em><em>m</em><em>.</em>
<u>Area of a rectangle</u>= Length × Width
=18cm×26cm
= 468cm².
Answer:
Savings of Jeff will be $140.
Step-by-step explanation:
List price of TV = $700
Now, it is given that, this TV is available at 20% off or 20% discount during the President's week.

Answer:
For an equilateral triangle, we know that all 3 sides of the triangle are equal. Accordingly, all the 3 sides of the equilateral triangle hold equal angles.
Since, we know, that the sum of all angles of any triangle be 180° .
Let each angle be a.
Thus,
Hence, we can show that all the 3 angles of an equilateral triangle hold equal angles; i.e. 60°.
