Answer:
Area = 
square feet
Step-by-step explanation:
The area of a rectangle is given by the formula:
A = length * width
Where length is 91 feet and width is 
feet
Before we do the multiplication, we have to change the mixed number [width] into an improper fraction by using the rule shown below:
Hence,
So, the area is:
Area = square feet
<h3>The length of rectangle is 12x³ metres .</h3>
As we know that
♦ Area of rectangle = Length × breadth
Substituting known values ,
⇒ 144x⁴ = 12x ( Length )
⇒ 144x⁴ / 12x = Length
⇒ 12x³ = Length
⇒ Length = 12 x³
Answer:
x = 5, y = 2
Step-by-step explanation:
First, find the value of x in respect to y:
2x + 3y = 16
2x = 16 - 3y
x = 8 - 3/2y
Then, substitute this expression into the second equation (Since we've established x is equal to 8 - 3/2y, we can put that in place of x):
4(8 - 3/2y) + 10y = 40
Then, distribute and solve for y:
32 - 6y + 10y = 40
32 + 4y = 40
4y = 8
<u>y = 2</u>
Now that we know what y equals, we can substitute the value of y in the equation to find x:
2x + 3(2) = 16
2x + 6 = 16
2x = 10
<u>x = 5</u>
