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

Area of the rectangle =

Step-by-step explanation:

Perimeter of the rectangle= 128 cm

Ratio of length to width is:

Area of the rectangle= Length*Width

Area of the rectangle =

960 cm^2

Step-by-step explanation:

length: width

5  :3

Multiply by x

5x  ; 3x

The perimeter of a rectangle is found by

P =2(l+w)

128 = 2 (5x+3x)

Combine like terms

128 = 2(8x)

128 = 16x

Divide each side by 16

128/16 = 16x/16

8 =x

length : width

5*8:  3*8

40 : 24

We need to find the area

A = l*w

  = 40*24

   =960

“ a line segment that has the endpoints on the circle and passes through the midpoint is called the diameter. the diameter is twice the size of the radius. a line segment that has its endpoints on the circular border but does not pass through the midpoint is called a chord. a circle is the same as 360 small circle up the number 0 . i hope this .

the answer is 18 units because there are 18 small cubes inside the rectangle

hope this and p.s i am also in k12
