Answer: P = 25n + 35
Step-by-step explanation:
The perimeter of a rectangle is twice the sum of length and width.
P = 2(l +w)
P = 2((8.5n+9) + (4n +8.5))
P = 2(12.5n +17.5)
P = 25n + 35
Answer: 55.56
Step-by-step explanation:
Let the unknown number be k
(45 x k) / 100 = 25
45k/100 = 25
multiply both sides by 100
45k = 25 x 100
45k = 2500
divide both sides by 45
k = 2500/45
k = 55.56
Answer:
17.98 square meters
Step-by-step explanation:
find the area of rectangle
length x width
6.2x1.8= 11.16
find area of triangle
base x height x 1/2
base= 6.2
height= 4-1.8= 2.2
area=2.2 x 6.2 x 1/2 = 6.82
add both together to get area of figure
6.82 + 11.16 = 17.98
To get the decimal you have to divide the numerator by the denominator.
-19÷-50=-0.38
-19/50=-0.38
