Answer: 25
Assuming the dotted line touches the middle of the base of the triangle,
Using Pythagoras Theorem,
(30/2)^2 + (20)^2 = x^2
x^2 = (15)^2 + 400
x^2 = 625
x = √625 or -(√625)
x = 25 or -25
But since x needs to be a positive value,
x = 25
So remember that (a/b)(c/d)=(ac)/(bd)
convert to imporoper number for easy
4 and 1/4=4+1/4=16/4+1/4=17/4
2 and 2/3=2+2/3=6/3+2/3=8/3
length times base=17/4 times 8/3=
(17 times 8)/(4 times 3)=
136/12=
34/3=
33/3+1/3=
10+1/3=
10 and 1/3 square yards
area is 10 and 1/3 square yards
Answer:
Height=12 Units
Step-by-step explanation:
Given a parallelogram with base b, and a perpendicular height, h. The area of the parallelogram is derived using the formula:
Area of a parallelogram=Base X Perpendicular Height
Given an area of 72 Units Squared.
Since I am not certain of the length of the base given:
If b=6
Area=bh
72=6h
Dividing both sides by 6
h=12 Units.
Height=12 Units
You can use the given formula to solve for the height,h of the parallelogram given any base b.
