A company logo is made up of a square and three identical triangles.
IgorLugansk [536]

Answer:

the \: area \: of \: the \: logo \: is \:  {91cm}^{2}

Step-by-step explanation:

To determine the area of the logo you have to calculate the area of the triangle and the square that comform it and then add the four areas.

Area of the square.

To calculate the area of the square you have to calculate the square of one of its sides, following the formula:

a =  {a}^{2}

Where "a" is the length of one of its side.

The side length of the square is a=7cm, so its area will be:

asquare =  {7}^{2}  \\ asquare =  {49cm}^{2}

Area of the triangles.

The three triangles are equal, they have a base equal to the side of the square, i.e. with a length of 7cm, and their height is h=4cm.

To calculate the area of one triangle, you have to multiply its base by its height and divide by 2, following the formula:

a =  \frac{b.h}{2}  \\  a =  \frac{7.4}{2}  \\ a =  \frac{28}{2}  \\ a =  {14cm}^{2}

The area calculated the correspond to one triangle, since all triangles are congruent, you have to multiply the said area by 3 to determine the area of three figures:

atriangles = 3a \\ atriangles =  {42cm}^{2}

Now that the area of all shape are calculated, you have to add them to determine the area of the logo:

alogo = asquare + atriangle \\ alogo = 49 + 42 \\ alogo =  {91cm}^{2}

janet is comparing prices of bottled water. one bottle of water costs $1.92 and contains 12 ounces. another bottle of water cost
AnnyKZ [126]

Bottle 1 = $1.92 & 12 ounces

Bottle 2 = $2.40 & 16 ounces

Bottle 1

If 12 ounces costs $1.92, to determine the price of 1 ounce we divide $1.92 by 12.

$1.92 ÷ 12 = $0.16 per ounce for bottle 1.

Bottle 2

If 16 ounces costs $2.40, to determine the price of 1 ounce we divide $2.40 by 16.

$2.40 ÷ 16 = $0.15 per ounce for bottle 2.

Therefore we can determine that Bottle 2 is cheaper per ounce than Bottle 1.
