diagonal of a rectangle with
dimensions 20 m by 15 m.
O the length of diagonal is 25m.
O the length of diagonal is 40m.
O the length of diagonal is 30m.​

Answer 1

Step-by-step explanation:

d^2 = base^2 + height^2

= 15^2 +20^2

= ✓625

diagonal= 25 m

hence the length of the diagonal is 25 m

Answer 2

Answer:

We know that diagonal of rectangle is hypotenuse of triangle when the rectangle is slashed into 2 right angled triangle.

So

By pythagoras theorem

Diagonal^2 = 15^2 + 20^2

Diagonal ^2 = 225 + 400

Diagonal = √625

Diagonal = 25m
