Question

If x = 3 in.and Y = 4 in.and what is the perimeter of the polygon blank in.

Answer 1

Plug in the values x = 3 and x = 4 and add up all the sides:-

= 4(4) + 4(3)^2 - 3(4)^2 + 3(3) + 3^2 + 2(4)^2 + 2(4)^2

= 16 + 36 - 48 + 9 + 9 + 32 + 32

= 86 answer

Answer 2

Perimeter of polygon is:

86 in.

Explanation:

Perimeter of polygon= 4y+4x²-3y²+3x+x²+2y²+2y²

= 4y+x²(4+1)+y²(2+2-3)+3x

= 4y+5x²+y²+3x

Putting x=3 in. and y= 4 in.

Perimeter of polygon= 4×4+5×3²+4²+3×3

= 16+45+16+9

= 86 in.

Hence, Perimeter of polygon is:

86 in.
