Answer:
The area of rectangle is 21 in^2
Step-by-step explanation:
we know that
The area of rectangle is equal to
where
L is the length
W is the width
In this problem we have
substitute
The draw in the attached figure
therefore
The area of rectangle is 21 in^2
This triangle is an isosceles triangle because there are two angles which measure 54° and one angle which measures 72°
If you're talking about Egyptian, you have to put 9 "ten" symbols on the paper and you get 90.
The "ten" symbol looks like a tiny arch.
Use the simple perimeter formula.
P = 2L + 2W
P = 2(9) + 2(5)
P = 19 + 10
P = 29ft
Therefore 29ft of fencing will be needed.
Triangles with a 90 degree angle. We use the sine, cosine and tangent functions to determine the missing angles and sides.
