Answer:
Length=22.5cm, Breadth=11.5cm
Step-by-step explanation:
Let length be l and width be w.
w+22=l
w+w+w+22+w+22=90
4w=90-22-22
=46
w=46 divided by 4
=11.5
l=11.5+11
=22.5
Hence,
Length of rectangle=22.5cm
Breadth of rectangle=11.5cm
Since this is a right triangle, we can you the pythagorean theorem.
a^2 + b^2 = c^2
In this case,
a = 6
b = ?
c = 10
We need to substitute our values into the pythagorean theorem.
(6)^2 + b^2 = (10)^2. Reduce everything to its simplest form.
36 + b^2 = 100. Subtract 36 from both sides.
b^2 = 64. Take the square root of each side.
b = 8.
make a proportion
<span>Let x = the amount of feet descended in 3 minutes (thus the total change of altitude of the balloon)
</span><span> 320 (feet per minute) / 1 (minute) = x (feet per minute) / 3 (minutes)
</span><span> 1) Divide: 320/1 = 320.
</span><span> 2) Multiply: 320 x 3= 960.
</span><span> The balloon that descends at a rate of 320 feet/minute (so, every minute, it descends 320 feet) descends a total of 960 feet in 3 minutes.
</span><span> The balloon's total change in altitude is -960 feet. </span>
