Well area of a triangle is
$\frac{1}{2} b \times h$
so,
$36 \times 2 = 72 \\ 72 \div 9 = 8$
The answer is 8

Decrease 248 by 30%

Snowcat [4.5K]

Okay this equation really says is what is 30% of 248.

So, lets convert 30% to a fraction, 3/10 which is easier to work with.

All you have to do now is get out a calculator and do 248 *3/10 (or .3) and get 74.4

So subtract 74.4 and get

173.6
