Question

Balvinders father had a rhombus shaped plot with diagonals of 20 and 40 motors long . He sold the plot and bought a square shaped plot of same area. Find the perimeter of new plot

Answer 1

Area of rhombus shaped plot=1/2*20*40=
1/2*800=400motors
Side of square plot=√400=20
Perimeter=20*4=80

Answer 2

area of field = 1÷2×d1×d2
= 1÷2×20m×40m
400 square metre

area of new squared field =400 square metre
side ×side =400 square metre
side =20 metre
perimeter of field =4 ×side
=4 ×20m
=80m
