Answer 1

Answer:

Use pythagoras theorem

Answer 2

Answer:

hiiii mate

let length of the rectangle is 20m

diagonal of a rectangle is 29m

in triangle ADC

AC^2. =. AD^2. +. DC^2

(29)^2. =. X^2. + (20)^2

841. =. X^2. + 400

X^2. =. 441

X. = 21m

the breadth of the rectangle 21m

perimeter = 2(l+b)

= 2 ( 20 + 21 )

= 2(41)

= 82m
