Question

perimeter of a rectangular plot is 860 m
length is 4 more than its breadth and find
its length and breadth​

Answer 1

Answer:

perimeter =2(length + breadth)

take breadth as a

take length as a+4

2(a+a+4)=perimeter

2(2a+4)=

4a+8=860

4a=860-8

4a=852

a=852÷4

a=213

breadth =213

length =217

Answer 2

Answer:

length =217 ;breadth= 213

• let the breadth =x
• length = x+4
• A T O
• perimeter of reactangle =860
• =2(l+b) =860
• = 2(x+x+4)= 860
• = 2x+8+2x = 860
• = 4x+8= 860
• =4x= 860-8
• = 4x =852
• = x = 852÷4
• =x = 213
• breadth = 213 ,
• length = 4 = 213+4
• = 217
