Question

find the area of a rectangle whose one diagonal is 26cm and length if 24cm

Answer 1

Answer:

240

Step-by-step explanation:

we know that,

sides of rectangle makes 90degree,

diagonal and length make 90degree,

now according to Pythagoras theorem

a^2+b^2=c^2,

where,c^2= hypotenuse,

here diagonal is hypotenuse,

length=side of a rectangle.

now,

24^2+x^2=26^2 (where x = another side)

576+x^2=676

x=√676-576

x=√100

x=10cm

area = l*b

area=24*10

area=240cm sq
