The area of the triangle is 2\sqrt{3} = 3.4641 square feet.

Step-by-step explanation:

Step 1:

According to the Pythagorean theorem, the square of the hypotenuse will be equal to the sum of the squares of the other two sides.

In the given triangle, the hypotenuse is the side that is represented by c. The other sides on the triangle are represented by the values a and b.

Step 2:

Assume the other side of the triangle measures x units.

So according to the Pythagorean theorem,

4^{2} = (2\sqrt{3} )^{2} + x^{2} , x^{2} = 4^{2} - (2\sqrt{3} )^{2} .

x^{2}  = 16 - 12 =4, x =2.

So the other side of the triangle, b measures 2 feet.

Step 3:

The area of a triangle is half the product of its base length and height.

The base length of this triangle is 2\sqrt{3} feet and the height is 2 feet.

The area of the triangle= \frac{1}{2} (2\sqrt{3} )(2) = 2\sqrt{3} = 3.4641.

The area of the triangle is 2\sqrt{3} = 3.4641 square feet.

Sarah has a wall hanging in the shape of a parallelogram. What is the height of the wall hanging if its area and base are 300 sq
Anastasy [175]
Use the formula
Area= base times height.
You're given that area =300cm^2 and base=20 cm.
Plug these into the equation to get 300=20 x height. Now, you just need to solve for height. To do this, you need to undo the multiplication of b x h by dividing the area by the base.
So, h = 300/20

Prav is converting £257 into $. He knows that £1 = €1.11 and €1 = $1.22. How many $ will Prav get? Give your answer to 2 dp.
Ostrovityanka [42]

Answer:

$348.03

Step-by-step explanation:

£257 = €1.11 * 257

£257 = €285.27

€285.27 = $1.22 * 285.27

€285.27 = $348.0294

Round to 2 dp, $348.03
