Find the surface area

Step-by-step explanation:

I believe this is correct, if not feel free to elt me know and I will fix it. I'm sorry in advance if it is incorrect.

Step-by-step explanation:

Area of a triangle = 1/2 base x height

Area of a rectangle = length x breadth

The triangle has 4km and 8km

1/2 x 8 x 4 = 32÷ 2 = 16km². area of a triangle

7km x 9km = 63 km²

The surface area is basically everything joined together making it

area of a triangle x area of a rectangle = 16km² x 63km² = 1,008km².

let f (x ) is a function and c be a positive real number,   the graph of the function g (x ) = f (cx ) is represented as follows.

when, c > 1,   the function compresses it in the x - direction.

when, 0 < c < 1, the function stretches it.

the function is g ( x ) = (9x )2.

the heighest power of x in g ( x ) = (9x )2 is 2, so the parent function is square function.

the equation of parent function is f ( x ) = x 2 .

the function is g ( x ) = (9x )2 and the parent function is f ( x ) = x 2 .

so, the functions f and g have the following relationship.

g ( x ) = f ( 9x ).

compare the function g ( x ) = f ( 9x ) with g (x ) = f (cx ).

c = 9 ( > 1 ).

so, the function g (x ) = (9x )2 compresses it in the x - direction.
