Answer:

I think it helps you ⬇⬇

Step-by-step explanation:

Given sides=16cm and 12cm

To find length=?

By using pythagores theorem,

l²=s²+s²

l²=16cm²+12cm²

l²=256cm²+144cm²

l²=400cm²

l=√400cm²

l=20cm

Answer 2

Answer:

20 cm

Step-by-step explanation:

Given that

length(l)=16 cm

breadth(b)= 12 cm.

let the ABCD are the vertices of the rectangle.

If we draw the diagonal to the rectangle then we can find a right angled triangle.

then the hypotenuse of the triangle i.e, AD will be the diagonal of the rectangle so we need to find the length of the hypotenuse which is the length of the diagonal.

(hypotenuse)^2=(opp)^2 + (adj)^2

AD=√(16)^2+(12)^2

AD=√(256)+(144)

AD=√400

AD=20

          Therefore the length of the diagonal of the rectangle is 20 cm
