I’m soo confused, need some help pls??

Step-by-step explanation:

let length of small triangle=y

2(x+y)=21

x+y=21/2=10.5

also y=2x

as you can see from vertical rectangle.

x+2x=10.5

3x=10.5

x=10.5/3=3.5

y=2×3.5=7

length of large rectangle=x+y=10.5 cm

width of large rectangle=2x=2×3.5=7 cm

perimeter of large rectangle=2(10.5+7)=2×17.5=35 cm
