The perimeter of a rectangle is 128 cm, and the ratio of its sides is 5: 3. Find the area of ​​a rectangle
Juliette [100K]

Answer:

Area = 960 cm^2

Step-by-step explanation:

Perimeter (P) = 2 (l + w)

P = 2l + 2w

Let the length be 5x

Let the width be 3x

From the question, P = 128.

Therefore:

128 = 2l + 2w

Divide both sides by 2.

l + w = 64

Recall we said:

l = 5x

w = 3x

So then:

5x + 3x = 64

8x = 64

Divide both sides by 8

x = 64/8

x = 8.

Since x = 8

Length = 5x = 5*8 = 40cm

Width =3x = 3 * 8 = 24cm

Area of a RECTANGLE:

Area = length * width

Area = 40 * 24

Area = 960 cm^2

1/4 +1/3 divided by4/5
ad-work [718]

Answer:

2/3

Step-by-step explanation:

Do 1/3 divided by 4/5 first.

So we are going to flip 4/5 to 5/4. The equation is now:

1/4+1/3 times 5/4

Now we are going to do the multiplication since multiply and division is before adding and subtraction.

1/3 times 5/4 = 5/12

Now we have to add 1/4+5/12

With adding ( and subtracting) we have to find the common denominator which is 12

So now we have 3/12 + 5/12 = 8/12 which reduces to 2/3
