Question

Area of the parallelogram = 2 x Area of one triangle

Answer 1

Answer:

Step-by-step explanation:

Here we will discuss about the area and perimeter of the triangle.

● If a, b, c are the sides of the triangle, then the perimeter of triangle = (a + b + c) units.

● Area of the triangle = √(s(s - a) (s - h) (s - c))

The semi-perimeter of the triangle, s = (a + b + c)/2

● In a triangle if 'b' is the base and h is the height of the triangle then

Area of triangle = 1/2 × base × height

Similarly,

area and perimeter of the triangle

Area of the parallelogram

Here we will discuss about how to find the area of a parallelogram. To calculate area of parallelogram we need to remember the formula and solve step-by-step.

ABCD is a parallelogram with base (b) and altitude (h).

area of parallelogram,perimeter of parallelogram

Area of parallelogram = 2 × Area of ∆ABC

= 2 × 1/2 × base × height sq. units

= 2 × 1/2 × AB × CE sq. units

= b × h sq. units

= base × height sq. units
