Question

A rectangular field has a perimeter of 100 m the length of the field is 10 m more than the breath.find the area of the field

Answer 1

breadth = x
length = 10+x
perimeter = 2(l+b)
100 = 2(x+x+10)
100 = 2x+2x+20
100-20 = 4x
80 = 4x
80/4 = x
20 =x
...
breath = 20m
length = 30m
...
Area = L×B
area = 20×30
area = 600m^2

Answer 2

here's ur ans......hope it helps u out
