The actual area of the side of the ramp which is a right angled triangle is 62.5 square feet.
What is area of right angles triangle?
Area of a right triangle = 1/2 × base × height
where base and height are legs of the right angled triangle.
According to the given question:
Two inches in scale drawing equals 5 feet.
By unitary method 1 inch equals 2.5 feet
Hence height of the ramp = 4 x 2.5 feet = 10 feet
Similarly, base of the ramp = 5 x 2.5 feet = 12.5 feet
No, area of side of the ramp which is a right angled triangle
A = 1/2 x base x height
A = 1/2 x 12.5 x 10 sq feet
A = 62.5 sq feet
