Question

find the dimensiin of a rectangular field,if its perimeter is 100m and its length is 20m more thsn its breadth.

Answer 1

heya

here is ur answer

==========================

given :-

perimeter of rectangle :- 100

it's length = 20 +x

breadth = ??

➡let breadth be X

v all know that perimeter of rectangle = 2(l+B)

➡ substitute the values given

➡ 100.= 2(20+X +x)

➡100 = 40+4x

➡ 100-40 = 4x

➡60 = 4x

➡ X= 60/4

➡X = 15

hence the breadth of the rectangle given is 15 m

length = 20+15 = 35

=============================

hope it helps u..!!

Answer 2

HEYA.....✋✋✋✋✋✋

HERE IS YOUR ANSWER.............

PERIMETER==>2(LENGTH+BREADTH)
100====>2[20+b+b]
100====>2[20+2b]
100====>40+4b
100-40==>4b
60==>4b
b==>15m
l===>b+20
l===>15+20
l==>35m

hence,l=35m and b=15m

Hope my answer would help you
