Hello, himachuu!
You've done an admirable part of work already . . .
In this diagram, the area of a pentagon is 800 square centimeters.
What is the area of the green triangle in cm² ?
Round up to the nearest whole number.
i found the side length of the pentagon to be 21.56cm. . . . . Good!
An interior angle of a regular pentagon is 108°.
Hence, a base angle of the green isosceles triangle is 72°.
The height of the triangle is: . cm.
