Trapezoid abcd has vertices a (2, 4), b (5, 4), c (7, 1), and d (0, 1). what are the lengths of the sides ad and bc?

  √13 ≈ 3.61

Step-by-step explanation:

The distance formula is applicable.

  d = √((x2-x1)² +(y2-y1)²)

  AD = √((0-2)² +(1-4)²) = √(4+9) = √13

  AD ≈ 3.605513 ≈ 3.61

___

The trapezoid is isosceles, so AD and BC are the same length, 3.61.

answer: f = 32.2m

step-by-step explanation: that is the answer

hello :

by applying the distributive property :

6 × 4.3 = 6 × ( 4 + 0.3 )

            =   (6 ×   4) + (6 ×   0.3)

            = 24 + 1.8

6 × 4.3 = 25.8
