Question

The area of another rectangle is x² + 5x + 6. If one side measures (x + 2), what is the measure of the other
side?

Answer 1

• L=x+2
• We need B

$\\ \sf\longmapsto LB=Area$

$\\ \sf\longmapsto B(x+2)=x^2+5x+6$

$\\ \sf\longmapsto B(x+2)=(x+2)(x+3)$

• Cancel x+2

$\\ \sf\longmapsto B=x+3$
