Question

formula:
area of saqure?
area of rectangle?
area of right-angled triangle ?
area of triangle?

​

Answer 1

Area of square = side×side

Area of Rectangle = 2×(length+breadth)

Area of right angled triangle = 1/2 × AB × BC

Area of triangle = 1/2 × base × height

Answer 2

Step-by-step explanation:

Solution

1) Area of square is square of it's side

let a is side of square then

$area \: of \: square = {a}^{2}$

2)Area of rectangle is product of its length and breadth

let l and b is length and breadth then

$area \: of \: rectangle = l \times b$

3)Area of right angled triangle is half of the product of its product of length and breadth here length may be its altitude.

let l is length b is breadth then

$area \: of \: right \: angled \: triangle = \frac{1}{2} \times l \times b$

4) Area of triangle is half of product of its length and breadth

let l and b are length and breadth respectively then

$area \: of \: triangle = \frac{1}{2} \times l \times b$
