Question

What is the perimeter of ΔBDE?

2 Answer

  • a = √1² + 2²
    a = √1 + 4
    a = √5
    a ≈ 2.23

    b = 4

    c = √3² + 2²
    c = √9 + 4
    c = √13
    c ≈ 3.6

    P = a + b + c
    P = 2.23 + 4 + 3.6
    P = 6.23 + 3.6
    P = 9.83

    Perimeter of ΔBDE = 9.83 units

    i would like to see the picture to be exsact but you didnt put it up so that is ok

    i hope this helps :)
