Question

Please answer these three quistions ASAP !!!!!! 10 points 7th grade math

Answer 1

a) 14x+6

b)12
`x^(2)`+9x

c)Perimeter= 118 Area=840

Explanation:

a) 2*length+ 2*width---> 2(4x+3)+2(3x)=8x+6+6x= 14x+6

b)length* width---> 3x(4x+3)= 12
`x^(2)`+9x

c) Perimeter----> 14(8)+6= 118

Area--->12(
`8^(2)`)+9(8)=840
