Question

the perimeter of 35m wide rectangular field is 190 find its area

Answer 1

The perimeter of the rectangular field is 190
And it's width is 35
The formula to find the perimeter of rectangle is 2(l+b)
As length is unknown...let length be x
So substitute in the formula
2(l+b)=190
l+b=190/2
l+b=95
l+35=95
l=95-35
l=60
Then the formula to find the area of rectangle is l×b
l×b
60×35
2,100
2100 m^2 is the area of the rectangular field
