Question

Find the area of rectangle
whose length
is12 cm
and the length of one diagonal
is 15 cm.​

Answer 1

Answer:

Area = 108cm^2

Answer 2

Answer:

L=12 cm

H or diagonal(Hypotenuse)=15 cm

we know pythagoras theorem,

H^2=P^2+B^2

15^2=12^2+B^2

225=144+B^2

B= Rootover(225-144)

B= Rootover 81

B=9

Now, area of reactangle=L*B

                                       =12*9=108 cm^2
