Answer 1

\[area of triangle = \frac{ base \times height }{ 2 }\]
\[area of square = side ^{2}\]

area of shaded part = area of triangle - area of square

Answer 2

in the triangle: base = 30 and height=30
in the square: side = 15

can you solve it now ?

Answer 3

Base x Height / 2?

Answer 4

Base x Height / 2 is the area of the triangle

Answer 5

So- get the complete area first- correct?

Answer 6

yes you have to get the complete area of the triangle first
then the area of the square
subtract them to get the area of shaded region

Answer 7

675?

Answer 8

area of triangle = 30*30/2 = 900/2 = 450
area of square = 15^2 = 225

area of shaded region = 450-225 = 225
