Can someone explain what i have to do on this?

In this scale drawing, 1cm of the rectangle represents 1m. First, you have to measure the base and the height of the rectangle with a ruler that includes centimeters. Once you have the dimensions, you can figure out how long and wide the actual swimming pool is. In example, if one side of the drawing is 8 centimeters long, then the side of the pool is 8 meters long.

For part b, if a scale drawing had 1 cm representing 2m, the drawing would be smaller. There would be less length on each side because more meters are represented by each centimeter.

You will need to know the dimensions of the rectangle to do part c. If the side is 8 centimeters long in the original drawing, that equals 8 meters. In the new scale drawing, each centimeters represents 2 meters, so the side would only have to be 4 centimeters long.

I hope this helps :)

answer: option a.

step-by-step explanation:

you know that the quadrilateral opqr ( a four sided figure) is inscribed in circle. this means that all its vertices are on the circle.

then, by definition, the opposite angles of the quadrilateral are supplementary, this means that the sum of their measures is 180 degrees.

you can observe in the figure that the angles ∠opq   and the angle ∠orq   are opposite, therefore:

then, can be used to d to calculate the measure of ∠opq

answer: 4 meters

step-by-step explanation: to you understand 2/3 better you can do 1 divided by 3 = . then multiply that by the 2 which is .66666666666666667 then you would do 6 x .66666666666666667 which is 4.      

hope this .
