Answer:
Step-by-step explanation:
The last one 75d+105
Area of decagon is given by:
Area=1/2(nsr)
where:
n=number of sides
s=side length
r=height
thus the area will be given by:
Area=1/2(10*4*6.2)
Area=124 cm^2
Given:
Consider the given expression is
To find:
The radical form of given expression.
Solution:
We have,
Therefore, the required radical form is .
