Respuesta :
Area of a triangle is half the area of a rectangle. The area of the triangle whose base length is 10 ft and the height is 30 ft is 1500 ft².
What is the area of the triangle?
The area of a triangle is half the area of a rectangle, therefore, it's half the product of the base and height of the triangle.
We know about the formula of the area of a triangle, also, the length of the base(10 ft) and the height(30 ft) of the triangle is given to us, therefore, substitute the values in the formula of the area of the triangle,
[tex]Area\triangle = \dfrac{1}{2} \times base \times height[/tex]
[tex]= \dfrac{1}{2} \times 10\times 30\\\\=1500\rm\ ft^2[/tex]
Hence, the area of the triangle whose base length is 10 ft and the height is 30 ft is 1500 ft².
