Question

plz explain the answer of both of them​

Answer 1

Answer:

Step-by-step explanation:

1.The question asked is the figure given below have same perimeter and area

Like an object perimeter= x ,& area =y

∴x=y

So in fig A , the area of rectangle=3.6 * 4.5= l*b =,16.20

And perimeter=2(l+b)=2(3.6+4.5)=2(8.1)=16.20

Since , perimeter is equal to area of fig .a. therefore it's a equable figure

same as for fig 2

By using Pythagoras th. The perimeter of triangle will be 16

And it's area is 12

Therefore their area and perimeter are not equal they are not equable fig

2. So we can say

By using hit and trail method we must find y

1.1 will not equable as it's area will be 1o and peri will be 2.2

1o will not be equable because it's area will be 1oo and peri 4o

As for the 2.5 it's area will be 25 and peri which is also 25

∴2.5 is the ans .
