Question

The height of a triangle is $x^4+y^4$ and its base is $14xy$. Find the area of the triangle. [1 mark]

Answer 1

Area of triangle = $\frac{1}{2}$ $\times$ base $\times$ height [0.5 mark]
Given,
Height = $x^4+y^4$
Base = $14xy$
$\therefore$ Required area = $\frac{1}{2}$ $\times$ $(x^4+y^4)$ $\times$ $14xy$
= $7xy(x^4+y^4)$ [0.5 mark]
