Triangle TRI has a base of m centimeters and a height of n centimeters. Rectangle RECT has a length of n centimeters and a width
miskamm [114]

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.

A step by step answer please
Allushta [10]

Answer:

7.92 m.

Step-by-step explanation:

Mean height = ∑(f . x) / ∑f  where  x is the midpoint and f the frequencies

The midpoints for the heights are:

2 for frequency 8              ( 0 + 4)/ 2 = 2

6 for      ..           21

10 for    ..            12

14 for    ..              7

18 for   ..               2

So the mean is:

[(2*8) + (6*21) + (10*12) + (14*7) + (18*2) ] / (8 + 21+12+7+2)

= 396 / 50

= 7.92 m.
