Question

5. What will be the perimeter of a rectangle if its length
is 3 times its width and the length of the diagonal is
8V10 cm?
(a) 16V10 cm
(b) 15/10 cm
(c) 64 cm
(d) 24 10 cm​

Answer 1

Given:

Length= 8V10

Breadth=3(8V10)

=24V10

As we know the perimeter of the rectangle is = 2(l+b)

=2(8V10+24V10)

=2(32V10)

=64V10

Hence the perimeter of the rectangle is 64V10cm
