Question

The length and breadth of a rectangle are 10cm and 6cm respectively (a) what is the length of the diagonal? (b)Find the perimeter of the rectangle? (c) Find the area of the rectangle?​

Answer 1

let length be perpendicular and breadth be base

${h }^{2} = {p}^{2} + {b}^{2}$

h^2 = 10^2 + 6^2

h^2 = 100+36

h^2 = 136

h = underroot 136

so length of diagonal is underroot 136cm

(b) perimeter of rectangle is = 2 (l+b)

= 2 (10+6)

= 2×16

= 32cm

(c) area of rectangle is = l×b

= 10×6

= 60cm^2
