Answer:
KL = 16
Step-by-step explanation:
For this problem, JL is the sum of KL and JK. So we can say this:
JK + KL = JL
( 3x + 6 ) + ( 5x + 6 ) = 28
8x + 12 = 28
8x = 16
x = 2
So, now we can find KL:
5x + 6 = ?
5(2) + 6 = ?
10 + 6 = ?
16 = ?
So the length of KL is 16.
Cheers.
Answer:
20 square feet
Step-by-step explanation:
The length of a rectangular deck is five times it's width if the decks perimeter is 24 feet what is the decks area
Step 1
We find the Length and Width of the deck
Perimeter of a rectangle = 2L + 2W
The length of a rectangular deck is five times it's width
W = Width
L = Length = 5W
P = 24 feet
Perimeter = 2(5W) + 2W
24 = 10W + 2W
24 = 12 W
W = 24/12
W = 2 feet
Solving for L
L = 5W
L = 5 × 2 feet
L = 10 feet
Step 2
We find the area of the deck
Area of the deck(Rectangle) = Length × Width
= 10 feet × 2 feet
= 20 square feet
