Question

The area of right triangular board is 422.26 . If one of the sides containing right ange is 42.2 m
find the other side,​

Answer 1

Answer:    Hence the other side is 20 cm.  

Step-by-step explanation:

Alright, lets get started.

Please refer the diagram I have attached.

The area of a right triangle is given as : $422.26$

One side is given as : $42.2$

The formula for area of right triangle is :  $\frac{1}{2}\times base \times height$

So, the area will be : $422.26=\frac{1}{2}\times 42.2 \times b$

Multiply 2 in both sides

$2 \times 422.26=42.2 \times b$

$b=20$ cm

Hence the other side is 20 cm.   :   Answer
