Question

the lenghth of rectangle is 8 cm and each of its diagnals us 20 cm. the breadth of the rectangle is​

Answer 1

Answer:

length = 8cm

diogonal = 20cm

let the breadth be x

according to the question

(length) ^2 + (breadth)^2 = (diagonal)^2

(8)^2 + (x)^2 = (20)^2

64 + (x)^2 = 400

(x)^2 = 400-64

(x)^2 = 336

x = 18.33cm
