The given is a triangle and we can solve the problem using the equation shown below:
Area = 1/2*base*heigth
Where base = 2.9 cm
Height = 9 cm
Solving for the area, we have:
Area = 1/2*2.9*9
Area = 13.05 cm²
Divide 11.25 by (2/3). The answer is 16.875
The length of the diagonal wood beams is 10.3 feet
<h3>Pythagoras theorem</h3>
The square of the hypotenuse is equal to the sum of the square of the other two sides as shown:
c² = a² + b²
where;
- a is the horizontal height = 9feet
- b is 5 feet
Get the length of the diagonal wood beams.
c² = 9² + 5²
c² =81 + 25
c² = 106
c = 10.3 feet
Hence the length of the diagonal wood beams is 10.3 feet
