Elle drew rectangle that was 3 units wide and 4 units long drew different rectangle that has same permiter but a different area

Answers

Perimeter = 2(l + b) = 2(3 + 4) = 14 cm

So, different possible values of l and b with different area
(1,6) (2,5) (5,2) (6,1)

The perimeter is 14. The area is twelve. You could do 6*1, because 6*1 is six, but 6+6+1+1=14.

The length of the hypotenuse of a right triangle is 15 in. and one leg has length of 6 in. Find the length of the other leg.A. 9 in.
B. 12 in.
C. square root 189 in.
D. square root 261 in

Answers

Answer: C. square root 189 in.

Step-by-step explanation:

Given : The length of the hypotenuse of a right triangle is 15 in.

The length of one leg = 6 in.

Let x be the length of other leg, then

According to Pythagoras theorem ,we have

Hypotenuse² = Perpendicular² + Base²

$\Rightarrow\ 15^2=6^2+x^2\n\Rightarrow225=36+x^2\n\Rightarrow\ x^2=225-36=189\n\Rightarrow x=√(189)\ in.$

Hence, the length of the other leg is $√(189)\text{ in.}$

Thus , the correct answer is C. square root 189 in.
