Question

find the breadth of a rectangle whose length is 9cm and diagonal is 41cm. also Find its area...​

Answer 1

Answer:

40cm, 360cm^2

Step-by-step explanation:

Lenght: 9cm = a

Diagonal: 41cm = c

From The Pythogoras Theorm:

a^2 + b^2 = c^2

(9)^2 + b^2 = (41)^2

Therefore,

b^2  = (41)^2 - (9)^2

b = 40,

Therfore, The Breadth = 40cm,

Now,

Area = Length x Breadth

(9) x (40) = (360)cm^2
