Question

A rectangular field has a perimeter of 100m. The length of the field is 10 m more than the breadth. find the area of the field.
1- 600sq.m
2- 2150sq.m
3- 2375sq.m
4- 2560sq.m

Answer 1

Let breadth = x , length = 10 + x
Perimeter is the total lengths of all the sides added up basically :)
In a rectangle we have 2 lengths and 2 breadths.


Therefore,
Perimeter = 2*length + 2*breadth
We know perimeter = 100 , length = 10 + x , breadth = x
Sub it in and we get:
100 = 2 ( 10 + x) + 2x
