Question

3) Find the diagonal of rectangle whose length is 35 cm and breadth is 12 cm
Also find its perimeter.​

Answer 1

Answer:

Let the diagnol be AC

Let the length be AB = 35cm

Let the breadth be BC = 12cm

By pythagorous theorem,

AB^2 + BC^2 = AC^2

(35)^2 + (12)^2 = AC^2

1225 + 144 = AC^2

AC^2 = 1369

AC = Root of 1369

AC = 37cm

Perimeter = 2(l+b)

                 = 2(35+12)

                 = 2(47)

                 = 94cm

Answer 2

Answer:

diagonal of rectangle =37 cm and perimeter =94 cm

Step-by-step explanation:

perimeter of rectangle =2[l+b]

given,

length = 35 cm

breadth = 12 cm

=2[35+12} = 94 cm

diagonal of rectangle = √l²+b²

√35²+12² = 37 cm
