3. The diagram shows a piece of rectangular tile PQRS. A kite shape TUVW is inscribed in the
rectangle. Given that the perimeter of PQRS is
120 cm, find the area of TUVW.

432cm²

Step-by-step explanation:

If the Perimeter is 120cm, PT=8 (120-28-12-12-28-12-12)/2

This means the rectangle is 24x36.

area of a kite is the diagonals divided by 2 (or half of the rectangle).

24x36=864

864/2=

432 cm²

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is
