The area of the proposed design, which is i n the shape of a right angle triangle, is 193.11 square feet.
What is a right-angle triangle?
It is defined as a triangle in which one angle is 90 degrees and the other two angles are acute angles. In a right-angled triangle, the name of the sides are hypotenuse, perpendicular, and base.
We know the area of the right angle triangle is given by:
[tex]\rm A = \dfrac{1}{2} \times L\times B[/tex]
From the proposed design:
L = 31.4 feet
B = 12.3 feet
[tex]\rm A = \dfrac{1}{2} \times 31.4\times 12.3[/tex]
A = 193.11 square feet
Thus, the area of the proposed design which is i n the shape of a right angle triangle is 193.11 square feet.
