Suppose the base and height are each multiplied by 1/2 .what effect would this have on the area ? h= 10 ft b= 14 ft

The area of the resulting figure is times smaller than the area of the original figure

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its areas is equal to the scale factor squared

I assume that the figure is a rectangle or a triangle

Let

z------> the scale factor

x-----> the area of the resulting figure

y----> the area of the original figure

so

we have

substitute

therefore

The area of the resulting figure is   times smaller than the area of the original figure

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
