Answer:
Step-by-step explanation:
Area = height * length
Let length of mural be x so height is 2/3x
Area = 2/3x*x = 600
x*x=900
x=30 feet
Length = 30 feet
Height = 2/3 *30 = 20 feet
Answer:
8 ft
Step-by-step explanation:
the ladder will make a right angle triangle with the house. The hypotenuse of the triangle is the ladder, 20 ft, and the height of the triagnle is 18 ft.
Solve for the base of the right angle triangle using pythagorean's theorem:
c=20, a=18, b=?



round to the nearest foot,
b = 8 ft
Area of roundabout = 153.86 yd2
we are given,
radius = 7 yd
Area of circle = π 
= 3.14 × 7× 7
= 153.86 yd2
<h3>
What is the area of circle?</h3>
The area of a circle is the space occupied by the circle in a two-dimensional plane. Alternatively, the space occupied within the boundary/circumference of a circle is called the area of the circle. The formula for the area of a circle is A = πr2, where r is the radius of the circle. The unit of area is the square unit,

Step-by-step explanation:
82 + 76 + 42 = 200
42 out of 200 hmmm
200 / 2 = 100
42 / 2 = 21
21 out of 100 = 42 out of 200
=
