If l is 30 units long and w is 10 units long, how long is the diagonal to the nearest tenth.

Therefore the diagonal is 31.6 unit.

Step-by-step explanation:

Given:

In a Rectangle

Length = L = 30 unit = Longer Leg

Width  = W = 10 unit  = Shorter Leg

Diagonal = d = Hypotenuse

To Find:

Relation between L ,W and d

d = ?

Solution:

In a Rectangle vertex angles are  90°

In Right Angle Triangle , By Pythagoras theorem we have

Substituting the values we get

i.e   .........Relation between L ,W and d

Now Substituting L = 30 ,W =10 we get

Therefore the diagonal is 31.6 unit.

yes the total will be same because in both of them the expression.is rearranged but their sign remains the same hence it hss just been shuffled
