Answer: C. 18 square unit.

Step-by-step explanation:

Since, By the diagram we can say that,

The polygon is made by 4 rectangles in which,

Measurements of these rectangle are, 3 × 1, 4 × 1, 1 × 3, 4 × 2.

Thus, the total area of the given polygon = Total sum of the Area of these rectangles

A= 3 × 1 + 4 × 1 + 1 × 3 + 4 × 2= 3+4+3+8=18 square unit.

Thus, The area of given rectangle = 18 square unit.

Therefore Option C is correct.

Solve for y Please help I need a tip

Gwar [14]

Answer:

y = 4

Step-by-step explanation:

Step 1: Write equation

9/4y - 12 = 1/4y - 4

Step 2: Solve for y

Subtract 1/4y on both sides: 8/4y - 12 = -4
Simplify: 2y - 12 = -4
Add 12 to both sides: 2y = 8
Divide both sides by 2: y = 4

Step 3: Check

Plug in x to verify it's a solution.

9/4(4) - 12 = 1/4(4) - 4

9 - 12 = 1 - 4

-3 = -3
