Question

fine perimeter and area​

Answer 1

Answer:

Step-by-step explanation:

As we can see in your 1st question

Two types of shapes are there in the diagram

1st is of right angled triangle ABE

2nd is of rectangle BCDE

Now, find perimeter of the figure for that

Formulas : perimeter of both rectangle and triangle is sum of all sides.

Perimeter of triangle ABE = 5 + 5 + AE

firstly, find AE side for that we can use here pythogorus theorem

Which means AB^2 + BE^2 = AE^2

Now put the values

(5)^2 + (5)^2 = AE^2

25 + 25 = AE^2

50 = AE^2

5root2 = AE
