Now, given that
a = 3 cm
tan A = 0.75
On substituting these values, we get
Cross multiplying, we get
Divide both sides by 0.75
10.125 or 10 and 1/8
to find the area of the triangle, you multiply length*width and divide by 2.
4.5^2 divided by two
20.25 divided by 2
10.125
0.89 hope you get it right!
