Answer:
Step-by-step explanation:
let, the length is z
thus the ratio will be 5z : 4z
perimeter = 2 (a + b)
360 = 2 ( 5z + 4z )
180 = 9z
z = 20 cm
length = 100 cm and width = 80cm
area = length * width
area = 100*80
area = 8000cm²
Answer:
x=19
Step-by-step explanation:
First, you place the numbers in place of the variables in their relative positions using the pythagorean theorem:
![15^{2} +x^{2}=24^{2}](https://tex.z-dn.net/?f=15%5E%7B2%7D%20%2Bx%5E%7B2%7D%3D24%5E%7B2%7D)
Then you square the numbers that you currently have:
![225+x^{2}=576](https://tex.z-dn.net/?f=225%2Bx%5E%7B2%7D%3D576)
Then subtract 225 from both sides to isolate the x:
![x^{2} =576-225](https://tex.z-dn.net/?f=x%5E%7B2%7D%20%3D576-225)
This gives you the equation:
![x^{2} =351](https://tex.z-dn.net/?f=x%5E%7B2%7D%20%3D351)
Then take the square root of both sides which gives you:
![x=18.7349939952](https://tex.z-dn.net/?f=x%3D18.7349939952)
Then round to the nearest whole number which gives you x=19
Answer:
D
Step-by-step explanation:
SA = bh + (s1 + s2 + s3)H is the formula to find out the surface area
b is base, h is height (small height), s's are the sides, H is the height (longer one)
SA = 12(9) + (10 + 10 + 12)32
SA = 108 + (32)32
SA = 108 + 1024
SA = 1132
