Question

Find the area of the triangle.

Answer 1

Answer:

Area of triangle = 1/2*b*h

$\frac{1}{2} * 2.8* 7.8\\\frac{1}{2} * 21.84\\\frac{21.84}{2}\\= 10.92$

Answer 2

Answer:

10.92 cm²

Step-by-step explanation:

The area (A) of a triangle is calculated as

A = $\frac{1}{2}$ bh ( b is the base and h the perpendicular height )

Here b= 2.8 and h = 7.8 , then

A = $\frac{1}{2}$ × 2.8 × 7.8 = 1.4 × 7.8 = 10.92 cm²
