Question

Find the length of the diagonals of a rectangle whose one side is 20 m and perimeter is 70 m.

Answer 1

Answer:

at first perimeter =70

side=20

other side=14

Answer 2

Answer:

perimeter of rectangle =2(l + b)

70=2(20+b)

70=40+2b

2b=70-40

2b=30

b=30/2

b=15

now,diagonal of rectangle =40-15

25

hence,the diagonal is 25
