Question

U the area of the field.
The length of a rectangle is 1cm more than its breadth. The
diagonal is 29 cm. Find the area of the rectangle.​

Answer 1

Step-by-step explanation:

let the breadth be xcm then length will be x+1cm.as this is a right Angeled ∆ .eq.

{x}^{2} + ({x + 1)}^{2} = {29}^{2}x2+(x+1)2=292

(by solving the eq. we get )

x=-21 & x= 20

as distance cannot be -ve.

so,x=20cm breadth is20cm & length is 21cm.

area of ∆is 1/2×b×h

so,1/2×20×21=210cm
