3

To calculate a fraction of a quantity, multiply the quantity by the numerator of the fraction and divide by the denominator

\frac{3}{4} of 20 = (3 × 20 )/4 = \frac{60}{4} = 15

\frac{3}{5} of 20 = (3 × 20 )/5 = \frac{60}{5} = 12

The two shapes have the same area. Work out the perimeter of the rectangle.
elena-14-01-66 [18.8K]
You need to do this in several steps.

1) Using the given length and width of the rectangle, find its area.
2) Then using the base and height of the triangle, find its area.
3) Since the areas are equal, set the expressions equal to each other, and solve for x.
4) Using the value of x you found, find the length and width of the rectangle and find its perimeter.

1) The area of the rectangle is A = LW
Area of Rectangle = (x + 2)x = x^2 + 2x

2) The area of the triangle is A = (1/2)bh
Area of Triangle = (1/2)(24)x = 12x

3) Set the areas equal and solve for x

x^2 + 2x = 12x

x^2 - 10x = 0

x(x - 10) = 0

x = 0 or x = 10

Since a width cannot be 0, we discard x = 0, and keep x = 10.

4) The length is x + 2 = 10 + 2 = 12
The width is x = 10

The perimeter is 2(L + W) = 2(10 + 2) = 2(22) = 44

The perimeter is 44 cm.

Which statement BEST explains the relationship between lines GF & HJ?
Pavel [41]

Answer:

Option (4)

Step-by-step explanation:

Slope a line passing through two points (x_1,y_1) and (x_2,y_2) is given by,

m = \frac{y_2-y_1}{x_2-x_1}

Since, blue line is passing through two points (-4, -2) and (0, 4),

Slope of the blue line = \frac{4+2}{0+4}

                                    = \frac{3}{2}

Similarly, green line is passing through two points (-4, 1) and (0, -2),

Slope of the green line = \frac{1+2}{-4-0}

                                       = -\frac{3}{4}

Since, \frac{3}{2}\neq -\frac{3}{4}

Neither these slopes are opposite reciprocals.

Therefore, both the lines are neither parallel nor perpendicular.

Option (4) will be the correct option.
