Answer:
4 cm
Step-by-step explanation:
Both the area of a square and the area of a rectangle can be found by multiplying length x width. Because all of the sides of a square are equal, you get 64 when you multiply two sides together to find the area.
Since the rectangle has the same area as the square, that means the rectangle's width has to be a number that equals 64 when multiplied by 16.
So, 64/16 equals 4.

Step-by-step explanation:
<u>Area Of The Triangle
</u>
(9)
The area of a triangle of base length B and height H is
provided the base and height are perpendicular to each other
(10)
The dimensions of the given triangle are not the ones needed to compute its area. We need to calculate the height of the triangle, and we have the hypotenuse of one of the identical right triangles. To find the height, we must apply Pythagoras's theorem:
Note the length of one leg of the triangle is half the length of the base. We need to solve for H:
Thus
(11)
Now we compute the area of the triangle
Answer:
y = -3/4x -4
Step-by-step explanation:
y = -3/4x + b
-1 = -3/4(-4) + b
-1 = 12/4 + b
-1 = 3 + b
-4 = b
y = -3/4x -4
You combine like terms so 5x + 3x= 8x and 2y + 4y = 6y so it is 8x + 6y
Answer:
The circumference is 66cm
Radius = Diameter/2
= 21/2 CM
= 10.5 CM
Circumference of a circle = 2πr
= 2 × 22/7 × 10.5 CM
