Answer:
The change in the area of the rectangle is 0 square feet
Step-by-step explanation:
To solve this problem we have to calculate the area of the two rectangles that give us
first we have to know the formula to calculate the area of a rectangle
a = area
l = length = 12ft
w = width = 5ft
a = l * w
we replace the known walues
a = 12ft * 5ft
a = 60ft²
we do the same with the other rectangle, but first we have to calculate its sides
w = 5ft - (5ft * 20/100)
w = 5ft - 1ft
w = 4ft
l = 12ft + (12ft * 25/100)
l = 12ft + 3ft
l = 15ft
a2 = 15ft * 4ft
a2 = 60ft²
to calculate the change in the area we subtract (a - a2)
a - a2 =
60ft² - 60ft² = 0ft²
By definition the area of a rectangle is:
A = w * l
The perimeter is:
P = 2w + 2l
Where,
w: width
l: long
Substituting values:
300 = w * l
80 = 2w + 2l
Solving the system of equations we have:
l = 30 m
w = 10 m
Answer:
The length and width of the field are:
l = 30 m
w = 10 m
Answer:
Midpoint (4|7)
Step-by-step explanation:
A(2,6) and B(6,8)
at first add the x values and divide it by two
(2+6)/2=4
second, add the y values and divide it by two
(6+8)/2=7
Midpoint (4|7)
-> and you can see it it is exactly in the middle of line segment
The shape has 9 sides.
Sum of interior angles = (n-2) x 180, where n is the number of sides.
Sum of interior angles = (9-2) x 180 = 7 x 180 = 1,260 degrees.
Step-by-step explanation:
According to the question,
l+5=2h
