Answer 1

c² = a² + b²

(A)
7,5² = x² + 4,5²
56,25 = x²  + 20,25
56,25 - 20,25 = x²
x² = 36
x = √36
x = 6
---------------
A=b*h
       2
A = 4,5*6 
          2
A = 13,5 cm²
----------------
Perímetro = 7,5+4,5+6
P = 18 cm
======================

(B)
x² = 5² + 12²
x² = 25 + 144
x = √169
x = 13
--------------
A=b*h
       2
A = 12*5
         2
A=30 cm²
--------------
P = 5+12+13
P = 30 cm
====================

(C)
w² = 16² + 12²
w² = 256 + 144
w = √400
w = 20
---------------
A=b*h
      2
A = 12 * 16 
           2
A = 96 cm²
--------------
P=16+1+20
P=48 cm
================
