Area of the rhombus, A = 22.5 sq. ft.

Step-by-step explanation:

The area of a rhombus = a. b

where, a = side of the rhombus

and b = height of the rhombus.

Here, the side, a = 5 ft

Height, b = 4.5 ft.

Therefore, area, A = 5 X 4.5 sq. ft

⇒ A = 22.5 sq. ft which is the required answer.

Nine yards of ribbon are cut into 8 equal pieces what is the length of each piece of ribbon. Write a division expression to repr

PSYCHO15rus [73]

Answer:

$x=\frac{9}{8}\ yards$

$x=1.125\ yards$

Step-by-step explanation:

Let's call x the length of each piece in yards

If the ribbon is cut into 8 equal pieces then the sum of the pieces is:

$x+x+x+x+x+x+x+x=8x$

Then:

$8x=9\ yards$

Now we solve the equation for x

$8x=9\ yards$

Divide both sides of equality by 8

$\frac{8}{8}x=\frac{9}{8}\ yards$

$x=\frac{9}{8}\ yards$

So the length of each piece is $\frac{9}{8}$ of a yard.

This is: 1.125 yards
