Question

Find the perimeter of the quadrilateral.

If x= 2, the perimeter is

inches

(4x2 + 8x) in.

31 in.

(3x2 - 5x + 20) in.

(7x+30) in.

Answer 1

129

Explanation:

Answer 2

The perimeter is 129 inches

Explanation:

we know that

The perimeter of a quadrilateral is the sum of its four length sides

Let

`a=(4x^2+8x)\ in\\b=31\ in\\c=(3x^2-5x+20)\ in\\d=(7x+30)\ in`

The perimeter is equal to

`P=a+b+c+d`

If x=2

then

Find out the value of each side

`a=(4(2)^2+8(2))=32\ in\\b=31\ in\\c=(3(2)^2-5(2)+20)=22\ in\\d=(7(2)+30)=44\ in`

substitute the values in the formula of perimeter

The perimeter is

`P=32+31+22+44=129\ in`
