Answer
Here the area and the width of the rectangular fence are given. We have to find length of the fence.
( diagram )
The area A of a rectangle is given by the formula A=lw where l is the length and w is the width.
Given that area is 500 square feet and width is 20 feet.
Substituting values in formula,
⇒500=l×20
⇒20/500
= 20/1×20
[ Dividing both sides by 20 ]
⇒l=25 feet
∴ length of rectangular fence is 25 feet.
Hence, the answer is 25.
Answer:
Below.
Step-by-step explanation:
7) c^2 = a^2 + b^2
15^2 = 11^2 + b^2
b^2 = 225 - 121 = 104
b = √104
= √4√26
= 2√26.m
8). 4^2 = a^2 + (√6)^2
a^2 = 16 - 6
a^2 = 10
a = √10.
You need 12 square roots of 1764 ?
Why not find the square root of 1764 first (it's 42) and then take 12 of those ?
Answer:Note that the Pythagorean Theorem only works with right triangles. You can use the Pythagorean Theorem to find the length of the hypotenuse of a right triangle if you know the length of the triangle's other two sides, called the legs.
Step-by-step explanation:Hope this helps :)
