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

AlladinOne [14]

Answer:

5 meters

Step-by-step explanation:

Based on the situation, it forms into a right triangle. So we will apply the Pythagorean Theorem here. The ladder acts as the hypotenuse while the height from the ground to the window serves as our side "a". We are tasked to solve for "b". Side "b" is the distance from foot of side a to the tip of side c which is the hypotenuse (ladder). We will derive the formula below to solve for b.

c = √( a² + b² )

c² = a² + b²

b² = c² - a²

b = √ ( c² - a² )

b = √ ( 13² - 12² )

b = 5 meters

Correct me if I'm wrong. I hope it helps.
