Question

a rectangle has a width of 20 inch and a diagonal of 29 inch find the length of the rectangle​

Answer 1

answer=21

Step-by-step explanation:

let length be x

given:

width=20inches

diagonal=29

according to phythogoras theoram:

(AB) ^2+ (BC) ^2=(CA) ^2

(x) ^2+20^2=29^2

x^2+400=841

x^2=841—400

x^2=441

x^2=21^2

x=21

therefore :

length=21inches
