Question

Base of triangle =(2x+3), height = (5x) what is area

Answer 1

`\boxed{ \tt{5 {x}^(2) + (15x)/(2) }}`

Explanation:

Area of triangle is calculated by 1/2 * base * height. We have the values of base and height. Substituting the values in order to find area:

= 1/2 * base * height

= 1/2 * (2x + 3) * (5x)

= 1/2 * (10x² + 15x)

= 5x² + 15x/2

~Area of the triangle is 5x² + 15x/2 (ans)

Answer 2

5x² + 15x/2

Explanation:

area = base × height/2

area = (2x + 3)(5x)/2

area = (10x² + 15x)/2

area = 5x² + 15x/2
