Question

What is the area of rectangular field? i. the perimeter of the field is 110 metres. ii. the length is 5 metres more than the width. iii. the ratio between length and width is 6 : 5 respectively?

Answer 1

perimeter =2(l+b)
110=2(l+b)......l+b=55
thenn . ,l=5+b.......2b=55-5.....b=25.....
then, l=30
area =lxb=30x25=750 sq.m

Answer 2

perimeter is equal to 2(l+b). and 110= 2(x+5+x) is 55=2x+5 and. 55-5=2x x is 25
