Answer:


\large\boxed{A=300\ cm^2}

Explanation:

The formula of an area of a parallelogram:


A=bh

b - base

h - height

Use the Pythagorean theorem to calculate a height h:


h^2+8^2=17^2


h^2+64=289 subtract 64 from both sides


h^2=225\to h=√(225)\\\\h=15\ cm

Calculate the area:


A=(20)(15)=300

Answer:

A) 300 cm2

Explanation:

First you have to find height

use Pythagorean theorem: a2 + b2 = c2


h^(2)+ 8^(2) = 17^(2)

h2 + 64 =289

h2 = 289-64

h2 = 225

h= 15

now the area

A = a * h

A = 20 * 15

A = 300 cm2
