AveGali [126]

Answer:

A)10.25 cm ; B)5 square cm  

Step-by-step explanation:

A)

Formula:

p=(a+b+c)         [p= perimeter ;  a,b , and c are the side lengths.]

∴The perimeter of the triangle =(4+2.75+3.5) cm  

                                                =10.25 cm

B)

Formula:

A = 1/2 . b .h    [A=area ; b= base ; h= height]

∴The area of the triangle = (1/2 . 4 . 2.5) square cm    [b=4 ; h=2.5]

                                         =5 square cm
