Question

the perimeter of a rectangle 60m .what would be its dimensions if its area be the maximum​

Answer 1

Answer:

Step-by-step explanation:

perimeter is 60m

that is 2(l+b) =60m

l+b=30m

30÷2=15(it is the middle no. which will give maximum area]

l+b = 30m-–--–-----––--–------––---–-––-(1)

Suppose l=15 m and b= 15m

so in equation (1) it is fit that is

15 +15 =30

now area of rectangle

l×b

15 ×15=225m^2

this is required answer
