Question

Write a simplified expression, in terms of y, for both area and perimeter of the triangle below

Answer 1

Answer:

Area: $27y^{3} -24y^{2}$

Perimeter: $6y^{2} +7y+5$

Step-by-step explanation:

Area:

$\frac{1}{2}$ x base x height

$6y^{2} (\frac{1}{2} )(9y-8)\\3y^{2} (9y-8)\\27y^{3} -24y^{2}$

Perimeter:

$6y^{2} +4y+(3y+5)\\6y^{2} +7y+5$
