Answer 1

The area of triangle = 3.8km²

Explanation:

Given :-

A triangle having length of base is 2km and length of height is 3.8km.

To find :-

• Area of triangle.

Solution :-

We know that ,

Area of triangle = ½ × Base × height

• Substitute the values.

Area of triangle = ½ × 2km × 3.8km

• Multiply 2km by 3.8km.

Area of rectangle = ½ × 7.6km²

• Divide by 2 .

Area of triangle = 3.8km²

Answer 2

Area of a triangle formula: 1/2 x base x height

Area = 1/2 x 2 x 3.8

Area = 3.8 square km
