Question

Use the diagram below to answer questions 1-6. All rooms are rectangular. 1. What is the value of side A? Explain your thinking. 2. What is the value of side B? Explain your thinking. 3. What is the value of side c? Explain your thinking. 4. What is the area of the vegetable garden? Show your thinking

Answer 1

Explanation:

1) A = x

Flower garden is in rectangular shape. In rectangle, opposite sides are equal.

2) The entire garden is in rectangular shape. In rectangle, opposite sides are equal.

B + x+ 4 = 10x + 6

Take x and 4 to other side to find the value of B. When taking to other side of equal to sign, the sign of x and 4 will change

B = 10x + 6 - x - 4

B = 10x - x + 6 - 4 {Combine like terms}

B = 9x + 2

3) C + x -2 = 5x -3

C = 5x - 3 - x +2

C = 5x -x - 3 + 2

C = 4x - 1

4) Area of Vegetable garden = length * width

= (5x - 3) * (9x + 2)

Use FOIL method

= 5x *9x + 5x*2 + (-3)*9x + (-3)*2

= 45x² + 10x - 27x - 6

= 45x² - 17x - 6
