i don’t understand this at all even just the answer for one would be really appreciated! it’s due soon

1. a= 23.7 in, b= 10.7 in, c= 26 in

a²= 562 in², b²= 114 in², c²= 676 in²

2. a= 21.7 cm, b= 7.21 cm, c= 22.9 cm

a²= 473 cm², b²= 52 cm², c²= 525 cm²

3. a= 22 in, b= 12 in, c= 25.1 in

a²= 484 in², b²= 144 in², c²= 628 in²

4. a= 37.7 m, b= 16m, c= 41 m

a²= 1425 m², b²= 256 m², c²= 1681 m²
