Answer 1

A) Deo=√(Xb-Xa)²+(Yb-Ya)²=√(0+4)²+(0+3)²=√4²+3²=√16+9=√25=5 Deo=5

B) Dfg=√(2+5)²+(-5-4)²=√7²+(-9)²=√49+81=√130 Dfg=√130

C) Dhi=√(-1+1)²+(12-5)²=√0+7²=√49=7 Dhi=7

D) Djk=√(3+2)²+(-4+1)²=√5²+3²=√25+9=√34. Djk=√34

E) Dlm=√(3+4)²+(-4-3)²=√7²+(-7²)=√49+49=√98 Dlm=√98

F) Dnp=√(-√2-√2)²+(√2+√2)²=√(-2√2)²+(2√2)²=√(4x2)+(4x2)=√8+8=√16=4 Dnp=4

G) Dqr=√(-3-1)²+(3-3)²=√-4²+0=√16=√4 Dqr=4
