Find the area of the triangle

Cerrena [4.2K]

Answer:

Part 1) $P=204\ yd$

Part 2) $A=1,325\ yd^2$

Step-by-step explanation:

Part 1)

we know that

The perimeter of triangle is equal to the sum of its length sides

$P=54+97+53=204\ yd$

Part 2)

we know that

The area of triangle is given by the formula

$A=\frac{1}{2}(b)(h)$

we have

$b=53\ yd\\h=50\ yd$

substitute

$A=\frac{1}{2}(53)(50)=1,325\ yd^2$

a line with the slope of -2 passes through the point (1,7) what is the closest point on the line above (1,7) which has a whole n

deff fn [24]

The closest point above on this line is (0,9)

You can find this by using the rise over run method. Since the slope is -2, we can move to the next whole number point by observing the fraction 2/-1.

Rise = 2
Run = -1

If you start on the point (1,7) and rise two, it will bring you to (1,9), then you have to move back one space (or run) to (0,9).
