HARD

ANSWER

Let ABCD be the rectangle and AC be the diagonal as shown in the above figure:

It is given that the diagonal AC=125 m and length of AB=75 m

In △ABC, ∠B=90

Answer 2

Answer:

175

Step-by-step explanation:

given  length   = 25

          breadth = 7

area of rectangle = l x b

                             = 25 x 7

                             = $175km^{2}$
