Step-by-step explanation:

The complete question is

Bianca is trying to find the area of this rectangle. She already measured one side as  10 cm. Which other length(s) could she measure to use in her area calculation?

The picture of the question in the attached figure

we know that

The area of rectangle is equal to

$A=LW$

where

L is the length of rectangle

W is the width of rectangle

Remember that

The opposite sides of a rectangle are parallel and congruent and the measure of each interior angle is 90 degrees

That means---> The length and the width are perpendicular

In this problem we have

$L=10\ cm$

we have that

The width is equal to

$W=b=c$

so

The area of rectangle is equal to

$A=10b\ cm^2$  or $A=10c\ cm^2$

therefore

To find out the width, Bianca could measure segments b or c, because they form a 90 degrees angle with the length
