The area of a rectangle is 276.9 m². If the length is 15 m, what is the perimeter of the
valentina_108 [34]

Answer:

66.92\:\mathrm{m}

Step-by-step explanation:

The area of a rectangle is given by l\cdot w where l is the length of the rectangle and w is the width of the rectangle. Therefore, based on the information given, we can write the following equation to solve for the width:

15\cdot w=276.9,\\w=\frac{276.9}{15},\\w=18.46\:\mathrm{m}.

The perimeter of a rectangle is given by p=2w+2l. Therefore, the perimeter of the rectangle is:

2(15)+2(18.46)=\fbox{$66.92\:\mathrm{m}$}.

Emilie rides her bike x miles before she gets a flat tire. She walks 1/3mile to a bus stop and then takes a bus for 2 1/2miles.
ICE Princess25 [194]

Given :

Emilie rides her bike x miles before she gets a flat tire.

She walks 1/3 mile to a bus stop and then takes a bus for 2 1/2 miles.

To Find :

Which expression shows how many miles Emilie travels in all.

Solution :

We know, total distance covered is given by sum of all the distance she travelled.

Distance covered, D = x + 1/3 + 2 1/2

D = x + 1/3 + 5/2

D = (6x + 2 + 15)/6

D = (6x + 17)/6

Therefore, total distance travelled by Emilie is (6x + 17)/6 .
