​

Answer 1

Answer:

Step-by-step explanation:

Here is your answer

Let the Diagonal of the rectangle is x cm

Length = 15 cm

Breadth = 8 cm

As we know that

Diagonal ^2 = Length^2 + Breadth^2

$/x²=15²+8²/x²=225+64/x²=289/x=√289/x=17/$

Therefore Diagonal of the rectangle is 17 cm

≈225+64=AC²

≈289=AC²

AC=√289

AC=17 cm
