Question

The perimeter of a rectangle is 56 cm. If the sides are in the ratio 3 : 4, find the lengths of the four sides and the two diagonals.

Answer 1

Answer:

sides are 12 and 16 CM

diagonal are equal and is of 20 cm

Answer 2

Step-by-step explanation:

let breadth = 3x and length = 4x

then,perimeter =2(l+b)=56

-> 2(7x)=56

-> 14x = 56

x = 4

then length = 16 and breadth = 12

now to find diagonal

d1= d2

(d1)^2 = (length)^2+(breadth)^2

= 256+144

=(20)^2

then d1 = d2 =20
