Question

fencing the compound of a house costs rupees 5,452. if the rate is rupees 94 per meter. Find the perimeter of the compound. If the breadth is 10m. Find its length​

Answer 1

length = 19 m

Explanation:

total cost = 5452

cost per metre = rupees 94

metres = 5452 ÷ 94

= 58m

a = length

perimeter = 2 x (length + breadth)

58 = 2 x (length + 10)

58 = 2a + 20

2a + 20 = 58

2a = 58 - 20

2a = 38

a = 38 ÷ 2

a = 19

length = 19 metres
