What is the area of this rectangle ?
Answer choices are in the picture

Answer:
D) [tex]15x^8y^3[/tex]
Step-by-step explanation:
Area = Length * Breadth
Area = [tex]5x^6y^2*3x^2y[/tex]
Apply exponent rule: [tex]a^b*a^c=a^{b+c}[/tex]
Therefore,
Area = [tex]5x^{6+2}y^2* \:3y[/tex]
Area = [tex]5x^8y^2*3y[/tex]
Apply exponent rule as mentioned above:
Area = [tex]5x^8y^{2+1}* \:3[/tex]
Area = [tex]5x^8y^3*3[/tex]
Multiply 3:
[tex]15x^8y^3[/tex]
