Respuesta :
the area of a triangle = 1/2 base * height (basically half of a rectangle)
so 1/2 * 18 * 15.25 = 9*15.25 = 137.25
don't forget units so the answer is 137.25 inches squared
so 1/2 * 18 * 15.25 = 9*15.25 = 137.25
don't forget units so the answer is 137.25 inches squared
The area of the triangle is half the product of its base and height. The area of the triangle is 137.25 in².
What is the area of the triangle?
The area of the triangle is half the product of its base and height. It is given by the formula,
[tex]\rm \text{Area of triangle} = \dfrac{1}{2} \times base \times height[/tex]
As it is given that the base of the triangle is 15¹/₄ inches, while the height of the triangle is 18 inches. Therefore, the area of the triangle is,
[tex]\rm \text{Area of triangle} = \dfrac{1}{2} \times base \times height[/tex]
[tex]= \dfrac{1}{2} \times 15(1/4)\times 18\\\\\\ = \dfrac{1}{2} \times \dfrac{(15\times 4)+1}{4} \times 18\\\\\\= \dfrac{1}{2} \times \dfrac{61}{4} \times 18\\\\\\=137.25\rm\ in^2[/tex]
Hence, the area of the triangle is 137.25 in².
