The perimeter of a rectangle is 128 cm, and the ratio of its sides is 5: 3. Find the area of a rectangle

blondinia [14]

Answer:

Area of the rectangle = $15 cm^2$

Step-by-step explanation:

Perimeter of the rectangle= 128 cm

Ratio of length to width is:

$\frac{Length}{Width}= \frac{5}{3} \\\\Length=5 cm\\\\Width=3 cm$

Area of the rectangle= Length*Width

$=5cm*3cm\\\\=15cm^2$

Area of the rectangle = $15 cm^2$

Will mark brainliest Let f(x)=x2+3x+2 .

PSYCHO15rus [73]

METHOD 1
f(3) = 20
f(4) = 30
f(5) = 42
f(6) = 56

rate of change
f(4)-f(3)=10
f(5)-f(4)=12
f(6)-f(5)=14

then the average of change is 10+12+14 /3 = 12

METHOD 2 --- faster

rate of change = f(6)-f(3) / 6-3
= (36+18+2)-(9+9+2) / 3
= 36/3 = 12
