Difference between the area of the triangle and square is 25
Step-by-step explanation:
- Step 1: Find the area of the triangle given its 3 sides using the Heron's formula.
Area of the triangle =
where s = 
⇒ s = (6 + 8 + 10)/2 = 24/2 = 12
= 
=
=
= 24 sq. units
- Step 2: Find the area of the square with perimeter = 28 units.
Perimeter of the square = 4 × side = 28
⇒ Side of the square = 28/4 = 7 units
⇒ Area of the square = (side)² = 7² = 49 sq. units
- Step 3: Find the difference between the area of the square and triangle.
Difference = 49 - 24 = 25
Answer:
NOT PROPORTIONAL
Step-by-step explanation:
The given two fractions are:
and
.
Proportional fractions are those which have the same value when to reduced to the simplest form.
Consider two fractions
and
.
We say they are proportional if
.
Or, if
then we can say the fractions are proportional.
Here the fractions are:
and
.
LHS: 5 X 10 = 50.
RHS: 8 X 8 = 64.
Clearly they are not equal. So, we can say these two fractions are not proportional.
The miller needs 1-3/4 kg (or 1.75 kg) for two loaves.
Therefore the amount of flour needed for 1 loaf is
1.75/2 = 0.875 kg per loaf.
For 8 loaves, the amount of flour needed is
8*0.875 = 7 kg
Answer: 7 kg of flour is needed for 8 loaves.
Hello!
