Question

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

Answer 1

Answer:

D) $15x^8y^3$

Step-by-step explanation:

Area = Length * Breadth

Area = $5x^6y^2*3x^2y$

Apply exponent rule: $a^b*a^c=a^{b+c}$

Therefore,

Area = $5x^{6+2}y^2* \:3y$

Area = $5x^8y^2*3y$

Apply exponent rule as mentioned above:

Area = $5x^8y^{2+1}* \:3$

Area = $5x^8y^3*3$

Multiply 3:

$15x^8y^3$
