Please help me with this please!

length of a rectangle= 2 inches, width of a rectangle = 10 inches.

Step-by-step explanation:

length of a rectangle= 3w+4

Perimeter of a rectangle = 2(length+width)

24=2( 3w+4+w)

24/2 = 4w+4

12 =4w+4

8=4w

w= 8/4 = 2

l= 3w+4 = 6+4 = 10

the sum of all the angles in a triangle are equal to 180

so you can add   the 3 given angles together to equal 180:

5y + 2y + 2y = 180

or since all three angles have the same letter, combine the 3 angles to equal 180:

9y = 180

we need the options
