Question

What is the length of diagonal, if area of a rectangle is 168 cm2 and breadth is 7 cm?

Answer 1

Answer:

Step-by-step explanation:

Area of rectangle = l × b

168 = l × 7

l = 168/7

l = 24 cm

Diagonal can ve found by applying Pythagoras property to the right triangle contain the diagonal.

Let the diagonal be represented by D

This will be the Hypotenuse of the right triangle

So

D square = 7 square + 24 square

D square = 49 + 576 =625

D = √625

D = 25 cm
