Write the decimal represented by each model.
jekas [21]

There are 100 squares in the grid.

63 are shaded.

Number of squares shaded is the numerator (number on top of the decimal).

Total number of squares is the denominator (number at the bottom of the decimal).

\frac{63}{100}

Whenever the denominator of the fraction is 100, you can just take the numerator and put a decimal behind the number.

Therefore, the decimal represented would be 0.63.

Value of x

Computation:

We know that sum of all interior angle in triangle is 180°

So,

A rectangle's perimeter and area have the same value. The width of the rectangle is 6 units. What is the length of the rectangle
Sliva [168]

Answer:

The length ot rectangle is 3 units.

Step-by-step explanation:

The formula for perimeter is P = 2l + 2w and the area is A = l×w. Assuming that the perimeter and area have the same values so you have to compare it :

perimeter = 2l + 2w

area= l \times w

perimeter = area

2l + 2w = lw

let \: w = 6

2l + 2(6) = 6l

2l + 12 = 6l

12 = 6l - 2l

4l = 12

l  = 3 \: units
