Can you find the perimeter and area of the figure?

perimeter of triangle=48 units.

area of triangle=96cm²

perimeter = 46

Area = 96 units^2

Step-by-step explanation:

The given is a right triangle and in right triangle the square length of hypotenuse is equal to sum of other two sides's square length

12^2 + 16^2 = hypotenuse^2

144 + 256 = hypotenuse^2

400 = hypotenuse^2

20 = hypotenuse

The perimeter is equal to the sum of all side lengths

12 + 16 + 18 = 46

The area of a triangle is calculated by multiplying height to the base and that divided by two

16 × 12 ÷ 2 = 96 units^2

step-by-step explanation:

try remembering the steps

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
