The answer is letter C)
Because 3x6=18
18-1=17
Answer:
length = 9 in ; width = 4 in
Step-by-step explanation:
1) formula of the area of a rectangle
A = base x width
2) write an equation with the given informations:
w x (3w-3) = 36
3) solve the equation
- multiply W by 3w and -3
3w^2 -3w = 36
- divide the two members by 3
w^2 - w = 12
- add up -12 at the two members
w^2-w -12 = 12 -12
w^2 - w - 12 = 0
- find two numbers whose sum is -1 and whose product is -12 and factorise the equation
(w-4)(w+3) = 0
- find the two solutions
w-4 = 0
w = 4
w+3 = 0
w = -3
4)remember that a length can’t be negative.
w = 4 is the only solution
5) find the length
4x3 - 3 = 9

What is equilateral triangle?
A closed two dimensional figure with three sides and three angles is called triangle.
Based on sides of triangle, triangle can be classified as equilateral, isosceles and scalene
The triangle whose all sides and all angles are equal is called equilateral triangle. All the angles of equilateral triangle are 60°
Here,
Since the triangle is equilateral, angle of triangle is 60°
sin 60° = 
=
