The area of the field where the length of each side is increased by 10% is 48.4 .
Step-by-step explanation:
The given is,
A rectangle field has an area of 40
If one side of the field is 3 cm longer than the other side
The length of new area in each side is increased by 10%
Step:1
Let,
- One side of rectangle
- Other side of rectangle
From given.
- +3
Formula for area of rectangle,
40 = ( b+3) × b
40 = + 3b
Solving the above the equation,
b = 5 cm
l = 8 cm
Step:2
If the area of rectangle increased by 10%,
l = 8 + ( 8 × )
= 8.8
b = 5 + ( 5 × )
= 5.5
Area of rectangle is,
a = ( 8.8 × 5.5 )
= 48.4 square centimeters
Result:
The area of the field where the length of each side is increased by 10% is 48.4 , if a rectangle field has an area of 40 square centimeters and one side of the field is 3 cm longer than the other side.
Check the picture below.
let's recall that a kite is a quadrilateral, and thus is a polygon with 4 sides
sum of all interior angles in a polygon
180(n - 2) n = number of sides
so for a quadrilateral that'd be 180( 4 - 2 ) = 360, thus
I guess it f(2) I’m not sure
We want to see<u> how many gallons</u> of liquid we will have in the given mixture. We will find that there are 8 gallons of liquid in the mixture.
<h3>Adding two volumes:</h3>
In this problem, we create a mixture of 1 gallon of water with 7 gallons of juice.
Notice that gallon is a unit of volume, an extensive property (which means that if we add two things with volumes V1 and V2, the final volume is V = V1 + V2)
Then in this case the final volume of the mixture is just:
V = 1 gal + 7 gal = 8 gal
We will have 8 gallons of the mixture.
