Answer:

We have to evaluate

→ (2x)×(3y)×(4z)

Using Commutativity property of numbers,which states ----a b=ba

→ (x×2×3×y)×(4z)

→x×(6y)×(4z)

→x ×(y×6×4×z)----Again used Commutative property

→x × (y×24×z)

Using associativity property of numbers,which states

---a×(b×c)=(a×b)×c=(a×c)×b

→x ×(24 yz)--------(1)

Using commutative Property between x and 24 ,that is

(x)×(24)=24 x

Expression 1, can be written as

→24 xyz

Hence Proved

What is the approximate area of the circle that fits perfectly inside of the square? Use Pi = 3.14 and round to the nearest tent

Pani-rosa [81]

Answer:

$19.625\text{ cm}^2$

Step-by-step explanation:

GIVEN: A square with base $5\text{ cm}$ , a circle that perfectly fits inside square.

TO FIND: Approximate area of circle.

SOLUTION:

Consider the figure attached.

let the radius of circle be $x\text{ cm}$

radius of circle $=\frac{\text{length of base of square}}{2}$

$x=\frac{5}{2}\text{ cm}$

$x=2.5\text{ cm}$

Area of circle $=\pi(radius)^2$

$=3.14\times(2.5)^2$

$=19.625\text{ cm}^2$

Hence the area of circle that perfectly fits inside the square is $19.625\text{ cm}^2$

Two garden plots are to have the same area. One is square and one is rectangular. The rectangular plot is 4 meters wide and 16 m

AlexFokin [52]

side = 8 m

the area of the rectangle = length × width = 16 × 4 = 64 m²

the area of the square = s² ( where s is the length of a side ), hence

s² = 64 ( since areas are equal )

take the square root of both sides

s = √64 = 8 m
