The table shows the stopping distances for a car at different speeds. Speed Stopping distance
20 mph 15 metres
40 mph 45 metres
60 mph
90 metres
a) Look at the square grid below.
It shows the bar for the stopping distance at 20 mph.
Use the same scale to draw the bar for the stopping distance at 40 mph.
20 mph
40 mph
Stopping
distance
b) The bar for the stopping distance at 60 mph will not fit on the grid.
How many squares long should the bar be?

Step-by-step explanation:

I uploaded the answer to a file hosting. Here's link:

the area of a triangle is determined by the formula: base x height * 1/2

you'll need to assign a base to the triangle. based on the vertices given, the simplest base would be the line segment from (-2,1) to (2,1). the distance between any two numbers is found by just subtracting them. here, you should subtract the x values to find the distance of this side.

2 - (-2) = 4.

so the distance (aka the length of the base) is 4. the height of the triangle is the distance between the base and the highest point on the triangle which is (3,4). we should subtract the y values this time to find the height/distance.

4 - 1 = 3

so the height is 3.

base = 4

height = 3

hope this if needed hmu
