Answer:

Area of a triangle = \frac{1}{2} area of rectangle

Step-by-step explanation:

Given:

Height of triangle = n cm,  Base of triangle = m

Length of rectangle = n cm, Width of rectangle = m cm

Area of ΔTRI = \frac{1}{2}  base × height

                     =  \frac{1}{2}  ( m ) × (n)   ⇒ \frac{1}{2} mn

Area of Rectangle RECT =  Length × Width

                                          = m × n ⇒  = mn

Comparing Area of triangle and rectangle.

\frac{1}{2} mn =  mn

We can conclude that area of triangle is half of the area of rectangle.

The ratio of the numerator and denominator of a rational number is 2 : 7 and
Nadya [2.5K]

Answer:

6/21.

Step-by-step explanation:

let the rational number be 2x/7x.

2x + 4 / 7x - 2 = 10 /19

Cross multiply:

19(2x + 4) = 10(7x - 2)

38x + 76 = 70x - 20

96 = 70x - 38x

32x = 96

x = 3.

So the rational number is  2*3/ 7*3

= 6/21.
