Answer:
The length of the rectangle is 120 feet.
Step-by-step explanation:
The perimeter of a rectangle can be found using the formula: P = 2W + 2L, where P = perimeter, W = width and L = length. Since we know the value of two of the three variables, we can plug them into the equation and solve for the missing value ('L'): 400 = 2(80) + 2L or 400 = 160 + 2L. Using inverse (opposite) operations to isolate the variable, we get: 400 - 160 = 160 - 160 + 2L or 240 = 2L. We then divide both sides of the equation by 2 to get rid of the coefficient: 240/2 = 2L/2 or 120 = L. So, the length of the rectangle is 120 feet.
Answer:
b=4
Step-by-step explanation:
Lets a be lenght and b width. From text we have:
a=b+4
a*b=32
Put the first equation in the 2n, we get:
(b+4)b=32
b^2+4b-32=0
b^2+8b-4b-32=0
b(b+8)-4(b+8)=0
(b+8)(b-4)=0
So it must be b=-8 or b=4. We know that width cannot be negative, so it is 4.
Here I did all I can do rn
Area =l×w
15.4=7×w
15.4/7=7/7w
2.2=w
Therefore the length of the height or width is 2.2ft
