Question

area=(3x+5) base=4x ans
​

Answer 1

$\huge{\underline{\underline{\sf{\pink{Answer:-}}}}}$

Area of a Triangle = 1/2×base×hight

We have been given the base as 3x +5

and the height as 4x

Substituting the values in the formula, we get:

Area of a Triangle,

$\frac{1}{2} \times 3x + 5 \times 4x$

$= \frac{4}{2} \times 3 {x}^{2} + 4x$

The area of the triangle will be $= \frac{4}{2} \times 3 {x}^{2} + 4x$
