Question

Find the area of a triangle whose two sides are 22cm,26cmand the perimeter is 64 cm

Answer 1

third side = perimeter - the sum of two sides
                 
                 =64-48
                 
                  =16

Area = √s(s-a)(s-b)(s-c)
          = √32(10)(6)(16)
           = 175.27 cm²

Answer 2

Answer:

22 + 26 + x

x =  64 - 22 - 26

x =  16

Step-by-step explanation:

Formula = a+b+c    P = Perimeter

c = P-a-b
