The dimensions of the triangle are decreased to 75% of there original measurements what is the area of the new triangle ?

Area of the new triangle = 0.28125ab square units.

Step-by-step explanation:

Take an example of a right-angled triangle with sides a, b and c.

Where a is the height and b is the base and c is the hypotenuse.

Area of the original triangle is given by: × base × height

In our case, area =   × a × b

After the dimensions of our triangle have been decreased to 75%, new area becomes:

× 0.75a × 0.75b = 0.28125ab square units.

answer: it's a

step-by-step explanation:

the simplified form is

step-by-step explanation:

we want to simplify the expression,

let us change the middle bar to a normal division sign to obtain,

we multiply the first fraction by the reciprocal of the second fraction to obtain,

we factor to obtain,

we cancel the common factors to get,

we simplify to get,

the correct answer is b
