The length of a rectangle is twice its width. Find its area, if its perimeter is 7 1/3 cm The area of the rectangle is _sq. cm.
Harman [31]

Answer:

The area of rectangle is 2\frac{80}{81}\ cm^2

Step-by-step explanation:

we know that

The perimeter of a rectangle is equal to

P=2(L+W)

we have

P=7\frac{1}{3}\ cm=7+\frac{1}{3}=\frac{22}{3}\ cm

so

\frac{22}{3}=2(L+W)

\frac{11}{3}=(L+W) ----> equation A

Remember that

The length of a rectangle is twice its width.

so

L=2W ----> equation B

substitute equation B in equation A

\frac{11}{3}=(2W+W)

solve for W

W=\frac{11}{9}\ cm

Find the value of L

L=2(\frac{11}{9})

L=\frac{22}{9}\ cm

<em>Find the area of rectangle</em>

A=LW

substitute the values

A=(\frac{22}{9})(\frac{11}{9})

A=\frac{242}{81}\ cm^2

Convert to mixed number

\frac{242}{81}\ cm^2=\frac{162}{81}+\frac{80}{81}=2\frac{80}{81}\ cm^2
