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`
