Question

Please help me find the perimeter and area of this

Answer 1

21.2 units ; 28 sq.units

Explanation:

Let's start from the topmost point and go counter clockwise.

Slanted side =
`\sqrt{2^(2) + 2^(2)}` = 2.8 units

Vertical side = 3 units

Horizontal side = 7 units

Vertical side = 3 units

Slanted side =
`\sqrt{5^(2)+2^(2)` = 5.4 units

So, perimeter = 21.2 units

We can divide the figure into a rectangle(bottom) and triangle(top).

Total area = Rectangle + Triangle

= (3*7) + ( (1/2)*7*2 )

= 21 + 7 = 28
