Question

Write an expression for the area of the figure.
Area =

Answer 1

Respuesta:

$\frac{1}{3}{b}^{2} + \frac{1}{2} b$

Answer 2

Respuesta:

Area = (b²/3)  + b/2

Explicación paso a paso:

The expression for a triangle area is:

a = base * height / 2

in this case:

a = b * (2b/3 + 1) / 2

2a = b*2b/3 + b*1

2a = 2b²/3 + b

a = (2b²/3  +  b) / 2

a = (2b²/3) /2  + b/2

a = (b²/3) + b/2
