21 is 84% of 25

Convert the percentage (84) into a decimal by dividing it over 100:
$\frac{84}{100} = 0.84$

Divide 21 over 0.84:
$\frac{21}{0.84} = 25$

21 = 84% * x

21 = 84/100 * x

21 = 42/50 * x

21 = 21/25 * x

x = 21 * 25/21

x = 25

21 is 84% of 25.

Find the area of the triangle belowunits given are cm, cm^2, cm^3

zloy xaker [14]

Answer:

$A_T=150cm^2$

Explanation: We need to find the area of the triangle, We know that the area of any right triangle is:

$A_T=\frac{1}{2}(b\times h)$

Therefore in the information given we have the following:

$\begin{gathered} h=20\operatorname{cm} \\ b=15\operatorname{cm} \end{gathered}$

Therefore the Area of this triangle is as follows:

$\begin{gathered} A_T=\frac{1}{2}(b\times h) \\ \therefore\rightarrow \\ A_T=\frac{1}{2}(20cm\times15cm)=\frac{1}{2}(20\times15)cm^2 \\ A_T=\frac{1}{2}(300)cm^2=150cm^2 \\ \therefore\rightarrow \\ A_T=150cm^2 \end{gathered}$

Note! Units are centimeter-squared
