OlgaM077 [116]

Answer:

The length of rectangle is 6 units and the width is 1.5 units

Step-by-step explanation:

Let

L -----> the length of rectangle

W ----> the width of rectangle

we know that

The area of rectangle is equal to

A=LW

we have

A=9\ units^{2}

so

9=LW -----> equation A

A rectangle width is one fourth it’s length

so

W=\frac{1}{4}L ----> equation B

substitute equation B in equation A and solve for L

9=L(\frac{1}{4}L)

L^{2}=9*4

L^{2}=36

take square root both sides

L=6\ units

Find the value of W

W=\frac{1}{4}(6)

W=1.5\ units
