Question

A. find the area

b. find the perimeter​

Answer 1

Area= 4y^2 + 14y + 12

Perimeter = 10y + 16

Explanation:

Area of a reactangle = length × width

= (4y+6) × (y+2)

= 4y^2 + 6y + 8y + 12

= 4y^2 + 14y + 12

Perimeter of a rectangle = 2 × (a +b)

= 2 × ( 4y + 6 + y+ 2)

= 2 × ( 5y + 8)

= 10y + 16
