Question

Pls explain me this question

Answer 1

Perimeter is 4a= 400
a=100m

Diagonals bisect each other at 90 degree

Half of the diagonal will be =160/2=80m

By Pythagoras theorem, we get the other half of the diagonal as 60m

The length of the diagonal=2*60=120m

Area of the room bus = diagonal1* diagonal 2/2

Area = 160*120/2=9600msq

She will give 4800msq land to her children

Hope it helps you
