Answer:
Step-by-step explanation:
Area of polygon = area of square + area of triangle
Square:
Side = 12 cm
Area of square = side *side
= 12 * 12
= 144 sq.cm
Triangle:
base (b) = 12 cm
Height h = 19 cm
= 6 * 19
= 114 sq.cm
Area of polygon = 144 + 114 = 258 square cm
Answer:
(a)
(b)
(c) Answer of part a is equation of line which is parallel to y axis and in part by equation of line is
which is parallel to x axis
Step-by-step explanation:
We have given points are
(a) Equation of line is given x = -9
We have to find the equation of line parallel to x= -9 and passing through
x = -9 line is parallel to y axis and so slope will be infinite
Equation of line is given by
So
(b) Equation of line is given
This line is parallel to x axis so slope will be zero
So equation of line will be
(c) Answer of part a is equation of line which is parallel to y axis and in part by equation of line is
which is parallel to x axis
