Answer 1

Answer:

2350 cm

Step-by-step explanation:

let's name the triangle firstly,

then,

perimeter of triangle= sum of all sides

perimeter= A+B+C

Perimeter=(300+200) + (100+550) + 800 cm

perimeter=500+650 + 800

perimeter of∆ = 1950 cm

Now, we will calculate the perimeter of square

So, perimeter of square = 4×side

perimeter of ⬜ = 4×100 cm

= 400cm

now, the perimeter of whole figure =⬇️

perimeter of ∆ + perimeter of square

=> 1950+400

=> 2350cm.
