Amount of material =area
area of triangle=1/2 times base tiems ehighte

base=2 and 1/4
height=8 and 1/2
convert all to imporpoert
2 and 1/4=2+1/4=8/4+1/4=9/4
8 and 1/2=8+1/2=16/2+1/2=17/2
so we have
area=1/2 times 9/4 times 17/2
area=(1 times 9 times 17)/(2 times 4 times 2)
area=153/16
area=9 and 9/16

answer is 9 and 9/16 square units of material

At a sport clubhouse the coach wants to rope off a rectangular area that is adjacent to the building. He uses the length of the

Furkat [3]

Answer:

w < 8 meters ( w must be greater than 0 because length cannot be 0)

Step-by-step explanation:

One side with building is 23 meters, the other opposite side also will be 23 meters (with rope).

Let width (remaining 2 sides) be "w", he has AT MOST 39 meters of rope, so we can write:

Rope Needed = 23 + 2w < 39

Simplifying:

$23 + 2w < 39\\2w < 39 - 23\\2w < 16\\w < 8$

The range of possible values of w is $w$ meters (of course w has to be greater than 0)
