Question

Time to test brainly's mathmaticians

Answer 1

Answer:

Step-by-step explanation:

corner points are A(3,8),B(8,3),C(11,6),D(6,11)

AB=√((8-3)²+(3-8)²)=√(25+25)=√50=5√2

BC=√((11-8)²+(6-3)²)=√(9+9)=√18=3√2

CD=√((6-11)²+(11-6)²)=√(25+25)=√50=5√2

DA=√((3-6)²+(8-11)²)=√(9+9)=√18=3√2

area=length× width=5√2×3√2=15×2=30 sq units

Answer 2

Answer:

30

Step-by-step explanation:

Long side is square root of 50

Short side is square root of 18

Square root of 50 times the square root of 18 equals 30
