Answer 1

Step-by-step explanation:

for 12

Perimeter (P)

= 2( L + B)

= 2 ( 500 + 300)

=2 * 800

= 1600 cm

For 13

Area

= L * B

= 500 * 300

= 150000 cm²

Answer 2

Step-by-step explanation:

Since Promethean board is rectangle in shape,

So Given,

Dimensions of that board = 500 cm by 300 cm

Hence, Perimeter of the board = 2(l+b)

= 2(500cm + 300cm) = 2 × 800cm

= 1600cm (Ans)(i)

Therefore, area of that board = l × b

= 500cm × 300cm

[tex] = 150000 {cm}^{2} (ans)(ii)[/tex]

How to find the area of a parallelogram with 3 numbers?

Answers

the area of a parallelogram is the base x the hight

14.8 square feet is the area of the given parallelogram.

What is Area?

The area is the entire amount of space occupied by a flat (2-D) surface or an object's form. On a sheet of paper, draw a square using a pencil. It has two dimensions. The area of a form on paper is the area that it occupies.

The area of a parallelogram is given by the formula:

Area = base x height

where the base is the distance between two parallel sides of the parallelogram.

In this case, the height is given as 2 feet, but we need to find the base.

Since the parallelogram has two pairs of parallel sides, we can use the width of 7.4 feet as the base.

Therefore, the area of the parallelogram can be calculated as:

Area = base x height = 7.4 ft x 2 ft = 14.8 square feet

So, the area of the parallelogram is 14.8 square feet.

How many terms are in the expression 2a - c + 7d+ 15

Answers

Answer:

8c

Step-by-step explanation:

Answer:

4

Step-by-step explanation:

I just want to tell you what a term is because your going to really need it when you go into middle school. So a term is where there is a number or a a number with a variable with it or a variable by itself. For example if there is 4x + 6m + 3 + X you would have 4 terms because you have 4 numbers along with variables and a variable by itself and with some numbers which are Co -Efficient. Co-Efficient is when a number is with a variable the number along with the variable is called a Co-Efficient. Both of them together is called a term so now you know :) The whole equation is called an expression if a a number is by itself like 4 + 3m the 4 would be considered as a constant because its just a normal number standing by itself.

Divide both sides by - 6, reversing the symbol as a result of dividing by a negative quantity.

- 8 < x , thus

x > - 8

Answer:

x >-8

Step 1: Flip the equation.

Step 2: Divide both sides by -6.
