Question

plz help me Mates..... ​

Answer 1

Answer:

S1= ( a+b+c) /2

S1=(120+122+22) /2=264/2=132

A1 =√132*(132-120) *(132-122) *(132-22)

=√{132*12*10*110)}=√1742400

A1=1320 m²

_________________

S2=(24+26+22) /2=37

A2=√37*(37-24) *(37-26) *(37-22)

=√37*13*11*15) =√79365=281.72m²

Shaded Area= A1-A2= 1320-281.72=1038.28 m²
