Answer:
○ Length = 20 centimeters and Width = 5 centimeters
Step-by-step explanation:
Let the length = L
Then the width is L - 15
A = lw
100 = L(L - 15)
L² - 15L - 100 = 0
(L - 20)(L + 5) = 0
L - 20 = 0 or L + 5 = 0
L = 20 or L = -5
Since a length of a rectangle cannot be negative, we discard the solution L = -5 and keep the solution L = 20.
L = 20
width = L - 15 = 20 - 15 = 5
Answer: ○ Length = 20 centimeters and Width = 5 centimeters
An equilateral triangle is a triangle that has sides that are all equal. Every equilateral triangle is also an isosceles triangle. So any two 2sides that are = have equaled opposite angles. ... Therefore, since all three sides of an equilateral triangle are equal that means all three angles are equal, too.
