Question

6. If the base of a triangle is twice its altitude and the altitude is 2x, what is the area of the triangle?

​

Answer 1

A = 4x²

Explanation:

the area (A) of a triangle is calculated as

A =
`(1)/(2)` bh ( b is the base and h the altitude )

here h = 2x , so b = 2 × 2x = 4x

then

A =
`(1)/(2)` × 2x × 4x =
`(1)/(2)` × 8x² = 4x²
