A rectangle has an area of 170.2m2 One of the sides is 3.7m in length.
Work out the perimeter of the rectangle.​

here

Area = 170.2 M2

Area of rectangle = l *b

let l= 3.7m

170.2 = 3.7* b

b= 46m

now , perimeter = 2(l+b)

= 2( 3.7 + 46)

= 99.4 m

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
