Answer 1

Answer:

12. Angle B= Angle Q ( right angle)

AC= PR ( hypotenuse)

BC= QR ( base)

So by RHS rule both the triangles are congruent.

13.Let breadth of the rectangle = b m

Applying Pythagoras Theorem in triangle ABC,

We get, (AC)2 = (AB)2 + (BC)2

(25)2 = (24)2 + (b)2

625 = 576 + (b)2

625 – 576 = b2

49 = A2

√7x7 = b

∴ b = 7 cm

Now, perimeter of the rectangle

= 2(l + b)

= 2(24 + 7)

= 2(31)

= 62 cm

14. BC^2= AB^2 + AC^2

BC^2= 4^2 + 3^2

BC^2= 16+ 9

BC= square root of 25

BC= 5
