A rectangular exercise mat has a perimeter of 36 feet. The length of the mat is twice the width. Write and solve an equation to

denpristay [2]

Answer:

Part a) The length of the mat is $12\ ft$

Part b) The area of the mat is $72\ ft^{2}$

Step-by-step explanation:

step 1

Find the length

Let

L-----> the length of the rectangle

W---> the width of the rectangle

we know that

The perimeter of rectangle is

$P=2(L+W)$

$P=36\ ft$

$36=2(L+W)$

$18=(L+W)$ ----> equation A

$L=2W$ -----> equation B

substitute equation B in equation A

$18=(2W+W)$

solve for W

$18=3W$

$W=18/3=6\ ft$

Find the value of L

$L=2(6)=12\ ft$

step 2

Find the area

The area of rectangle is equal to

$A=LW$

substitute the values

$A=(12)(6)=72\ ft^{2}$

Why do people answer my question if they dont know the answer?

Bogdan [553]

Because people want points, so they answer as many questions as they can... it's quite stupid (and annoying), if you ask me.
