Algebra

The area of a rectangle, $A$`A`, is given by the formula $A=L\times W$`A`=`L`×`W`, where $L$`L` is the length and $W$`W` is the width.

If the length of a rectangle is $15$15 cm, select the expression that gives the area of the rectangle in terms of the width.

$A=\frac{15}{W}$`A`=15`W`

A

$A=\frac{15}{L}$`A`=15`L`

B

$A=15L$`A`=15`L`

C

$A=15W$`A`=15`W`

D

$W=15A$`W`=15`A`

E

$A=15+W$`A`=15+`W`

F

$A=\frac{15}{W}$`A`=15`W`

A

$A=\frac{15}{L}$`A`=15`L`

B

$A=15L$`A`=15`L`

C

$A=15W$`A`=15`W`

D

$W=15A$`W`=15`A`

E

$A=15+W$`A`=15+`W`

F
