The figure shown has a parallelogram on top and a rectangle below it:

anyanavicka [17]

Answer:

The area of the figure is $962.48\ in^{2}$

Step-by-step explanation:

we know that

The area of the figure is equal to the area of parallelogram plus the area of rectangle

Step 1

Find the area of rectangle

The area of rectangle is equal to

$A=LW$

we have

$L=42.4\ in$

$L=10.5\ in$

substitute

$A=42.4*10.5=445.2\ in^{2}$

Step 2

Find the area of parallelogram

The area of parallelogram is equal to

$A=bh$

we have

$b=42.4\ in$

$h=12.2\ in$

substitute

$A=42.4*12.2=517.28\ in^{2}$

step 3

Find the area of the figure

$445.20\ in^{2}+517.28\ in^{2}=962.48\ in^{2}$

Greata had a price of cloth that is 9 yards long. She cuts it into prices that are each 1/3 yard long. How many prices of cloth

KonstantinChe [14]

Given:

Length of cloth = 9 yards

Length of pieces = $\dfrac{1}{3}$ yards each

To find:

The number of pieces of cloths after cutting.

Solution:

Let n be the number of required pieces.

Length of each piece is $\dfrac{1}{3}$ yards. So, the length of n pieces is $\dfrac{1}{3}n$ yards.

The length of the whole cloth is 9 yards. So, $\dfrac{1}{3}n$ yards must be equal to 9 yards.

$\dfrac{1}{3}n=9$

Multiply both sides by 3.

$n=9\times 3$

$n=27$

Therefore, the Greata have 27 pieces of cloths.
