Mekhanik [1.2K]

Answer:

A

Step-by-step explanation:

Half the length of the third side, that is

x + 31 = 2(x + 19)

x + 31 = 2x + 38 ( subtract x from both sides )

The length of each square on the grid represents 1 cm. The scale
tatyana61 [14]

Answer:

Step-by-step explanation:

Length of the rectangle given in the the figure attached = 2 cm

Width of the rectangle = 5 cm

Scale used, 24 in to 1 cm

Therefore, length of actual rectangle = 2×24 = 48 in

width of the actual rectangle = 5×24 = 120 in

Now we have to draw a drawing by using the scale,

16 inches to 1 cm

Or 1 inch = \frac{1}{16} cm

Therefore, length of the rectangle drawing = 48\times \frac{1}{16}

                                                                        = 3 cm

Similarly, width of the rectangle drawing = 120\times \frac{1}{16}

                                                                    = 7.5 cm
