Answer:
225 inches²
Step-by-step explanation:
Let the length be l and width be w
Condition 1
2l+2w=68 (Perimeter=68)--------(i)
Condition 2
l=3w-2 ---------(ii)
Putting equation (ii) in (i)
2(3w-2)+2w=68
6w-4+2w=68
8w-4=68
8w=68+4
8w=72
dividing both sides by 8
w=9 inches
now putting w=9 in (ii)
l=3(9)-2
l=27-2
l=25 inches
Now
Area of rectangle = l × w
=9 × 25
=225 inches²
Answer:
x=9
Step-by-step explanation:
-5 square root x =-2+3
5x=4x^2 −12x+9
Simplify 25x-4{x}^{2}+12x-925x−4x 2 +12x−9 to 37x-4{x}^{2}-937x−4x 2-9
then...
(4x−1)(x−9)=0
x=1/4,9
-drop 1/4
x=9
