Question

The area of a rectangle is 300 square meter and perimeter is 74 meter.What is the diagonal length of the rectangle?

Answer 1

let the length be L and the breadth be B

therefore we have

2(L+B) = 74

or, L+B =37

and LB= 300

diagonal = √L²+B²

= √(L+B)²-2LB

= √1369-600

=√769

=27.73 m
