Step-by-step explanation:just do 4x+3

Because it is an equilateral triangle, all three sides are the same length.  Because of this, you need to divide 63/3 to find out the length of one side.  63/3=21.  So this tells us that 4x+3=21.  Now that we have the equation, we need to solve for x. To do this, subtract the 3 on both sides to get 4x alone.  21-3=18.  So now we know that 4x=18.  Now divide 4 on each side to get x alone.  X= 18/4, which simplifies to 9/2.  In decimal form, x=4.5.

A Japanese garden has a circular koi pond in the middle that has a radius of 3 feet. A rectangle with length of 16 feet and widt
Mariulka [41]

Answer:

first, find the area of the circle cut.

r= 3 feet

π=3.14

area of a circle= πr²= 3.14×3×3= 28.26 sq.feet

Now, find the area of the rectangle and subtract it by the area of the circle.

area of rectangle = l×b

length of the rectangle= 16 feet

breadth/width of the rectangular garden= 14 feet

area=  16×14= 224 sq. feet

now, area of the garden surrounding the koi pond=  224-28.26

                                                                                     =195.74 sq. feet
