I need help cuz Im not good at maths

Answers:

a. 26.2 cm

b. 13.8 cm

Steps:

a. Solution,

Length(l)=9 cm

Breadth(b)=4.1 cm

Perimeter of rectangle=2(l+b)

=2(9+4.1)

=2*13.1

=26.2 cm

b. Perimeter of triangle=a+b+c

= 3.6+3+7.2

=13.8 cm

Hope it helps

Good luck on your assignment

Step-by-step explanation:

Picture A

there is a rectangle in picture a.

So, let's find the perimeter of this shape

Picture B

there is a triangle in picture b

So, let's find the perimeter of the triangle.

To find the perimeter of a triangle you have add the values of three sides together.

hope this helps

good luck! have a nice day!

the required function is .

step-by-step explanation:

from the given table it is noticed that the graph passing through (-3,7), (0,4), (3,1) and (8,-4).

it is a linear function because the value of y is decrease by one as the value of x increase by 1.

the slope of the function is

the slope of the function is -1 and the y-intercept is 4.

the slope intercept form is

where, m is slope and b is y-intercept.

therefore the required function is . the graph of this function is shown below.

4 and 5)16.97 or 12√2

6)15.59 or 9√3

7)y = 15.59 or 9√3     x =27

8)17.80
