Answer 1

A = ( B + b ) h

-------------

2

Donde:

A = Área

B = base mayor

b = base menor

h = altura

Entonces:

A = ( 12 + 5) 17 119

-------------- ×7 = ---------- ×7 = ------- = 59.5 cm²

2 2 2

A = 1

---- × BC × AB

2

Entonces:

AB = 1

----- ( 5 - 4 ) 3

2

A = 1x - 3²

-----

2

A(x) = 1x - 3² 1 - x = 0

---- x = 1

2

A" (x) = -1

A = 1x - 3²

----

2

A = 1(3) - (3)²

-----

2

A = 9

----- = 4.5 cm²
