Question

Find the area of the triangle.

Answer 1

Area of triangle = 1/2*b*h

`(1)/(2) * 2.8* 7.8\\(1)/(2) * 21.84\\(21.84)/(2)\\= 10.92`

Answer 2

10.92 cm²

Explanation:

The area (A) of a triangle is calculated as

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

Here b= 2.8 and h = 7.8 , then

A =
`(1)/(2)` × 2.8 × 7.8 = 1.4 × 7.8 = 10.92 cm²
